Welcome to the Docsy theme user guide! This guide shows you how to get started creating technical documentation sites using Docsy, including site customization and how to use Docsy’s blocks and templates.
What is Docsy?
Docsy is a theme for the Hugo static site generator that’s specifically designed for technical
documentation sets and has a lot of best practices built in. Use Docsy to get a working and reliable documentation
site up and running fast, and then get back to focusing on great content for your users.
Learn more about Docsy.
In addition to the theme itself, we provide an example site that uses lots of Docsy features and has a useful skeleton site structure (with advice for what to put in it!) for a large technical documentation set. You can copy the entire site and edit it for your own projects, or just explore the site and its source to see what Docsy can do. The site you’re currently reading also uses Docsy and is a useful example of a smaller Docsy docset: feel free to copy it or borrow from it if it suits your needs better than the “big” example.
Docsy itself does not provide:
Source hosting and management: Our theme and site source files live on GitHub, which is the simplest approach for most projects. However, you can also keep your project files in GitLab, BitBucket, locally, or wherever you like. Be aware that where your source files live may affect the Docsy features you can use (such as letting users file documentation issues) and site deployment options.
Docsy also doesn’t actually generate your site’s HTML files: that’s Hugo’s job! Hugo takes your Markdown or HTML doc source files and Docsy’s theme files and builds them into a static site for deployment. You can find out more about Hugo and how it works in the Hugo documentation.
Is Docsy for me?
Docsy is particularly useful for medium to large technical documentation sets with 20+ pages of docs and/or multiple types of docs and pages: tutorials, reference documentation, blog posts, community pages, and so on.
If you have a smaller project with only a couple of pages of documentation and hence simpler navigation needs, Docsy may be too heavyweight a solution for you. Instead, consider:
A good README file that tells users what your project does and links to some examples.
If you have a very large documentation project, our example site structure may not be sufficient either, though you can still use our theme, possibly with heavier customization.
If you’d like to use Docsy’s layouts but prefer to use Jekyll, vsoch has created a Docsy Jekyll port that includes many of Docsy’s features (though as this is a separate project it won’t be automatically updated along with Docsy).
Learn how to get started with Docsy, including the available options for installing and using the Docsy theme.
As you saw in our introduction, Docsy is a Hugo theme, which means that if you want to use Docsy, you need to set up your website source so that the Hugo static site generator can find and use the Docsy theme files when building your site. The simplest way to do this is to copy and edit our example site, though we also provide instructions for adding the Docsy theme manually to new or existing sites.
If you want to build and test your site locally you also need to be able to run Hugo itself, either by installing it and any other required dependencies, or by using our provided Docker container.
This page describes Docsy’s installation options and helps you choose the appropriate setup guide to get started.
Installation options
Hugo offers multiple options for using themes, all of which are supported by Docsy.
Adding the theme as a Hugo Module: Hugo Modules are the simplest and latest way to use Hugo themes. Hugo uses the modules mechanism to pull in the theme files from the main Docsy repo at your chosen revision, and it’s easy to keep the theme up to date in your site. Our example site uses Docsy as a Hugo Module.
Adding the theme as a Git submodule: Adding the theme as a Git submodule also lets Hugo use the theme files from their own repo, though is more complicated to maintain than the Hugo modules approach. This is the approach used in older versions of the Docsy example site and is still supported.
Cloning the theme files: If you don’t want Hugo to have to get the theme files from an external repo (for example, if you want to customize and maintain your own copy of the theme directly, or your deployment choice requires you to include a copy of the theme in your repository), you can clone the files directly into your site source.
Migration and backward compatibility
If you have an existing site that uses Docsy as a Git submodule, and you would like to update it to use Hugo Modules, follow our migration guide. If you’re not ready to migrate yet, don’t worry! Your site will continue to work as usual.
Setup guides
Follow the setup guide for your chosen approach. If you’re new to Docsy and not sure which guide to follow, we recommend following the Use Docsy as a Hugo Module guide as a simple and easily maintained option.
1.1 - Use Docsy as a Hugo Module
Learn how to get started with Docsy by using the theme as a Hugo Module.
Hugo modules are the simplest and latest way to use Hugo themes like Docsy when building a website. Hugo uses the modules mechanism to pull in the theme files from the main Docsy repo at your chosen revision, and it’s easy to keep the theme up to date in your site. Our example site uses Docsy as a Hugo module.
To find out about other setup approaches, see our Get started overview. If you want to migrate an existing Docsy site to use Hugo Modules, see our migration guide.
Setup options with Hugo Modules
To use Docsy as a Hugo Module, you have a couple of options:
Copy and edit the source for the Docsy example site. This approach gives you a skeleton structure for your site, with top-level and documentation sections and templates that you can modify as necessary. The example site uses Docsy as a Hugo Module.
Build your own site using the Docsy theme. Specify the Docsy theme like any other Hugo theme when creating or updating your site. With this option, you’ll get Docsy look and feel, navigation, and other features, but you’ll need to specify your own site structure.
If you’re a beginner, we recommend that you get started by copying our example site. If you’re already familiar with Hugo or want a very different site structure, you can follow our guide to start a site from scratch, which gives you maximum flexibility at the cost of higher implementation effort. In both cases you need to follow our prerequisites guide to make sure that you have installed Hugo and all necessary dependencies.
1.1.1 - Before you begin
Prerequisites for building a site with Docsy as a Hugo Module.
This page describes the prerequisites for building a site that uses Docsy as a Hugo Module.
Install Hugo
You need a recent extended version (we recommend version 0.73.0 or later) of Hugo to do local builds and previews of sites (like this one) that use Docsy. If you install from the release page, make sure to get the extended Hugo version, which supports SCSS; you may need to scroll down the list of releases to see it.
For comprehensive Hugo documentation, see gohugo.io.
If you’ve already installed Hugo, check your version:
hugo version
If the result is v0.73 or earlier, or if you don’t see Extended, you’ll need to install the latest version. You can see a complete list of Linux installation options in Install Hugo. The following shows you how to install Hugo from the release page:
You can install Hugo as an npm module using hugo-bin. This adds hugo-bin to your node_modules folder and adds the dependency to your package.json file. To install the extended version of Hugo:
Hugo’s commands for module management require that the Go programming language is installed on your system. Check whether go is already installed:
$ go version
go version go1.17.6 windows/amd64
Ensure that you are using version 1.12 or higher.
If the go language is not installed on your system yet or if you need to upgrade, go to the download area of the Go website, choose the installer for your system architecture and execute it. Afterwards, check for a successful installation.
Install Git VCS client
Hugo’s commands for module management require that the git client is installed on your system. Check whether git is already present in your system:
git version
git version 2.35.1.windows.1
If no git client is installed on your system yet, go to the Git website, download the installer for your system architecture and execute it. Afterwards, check for a successful installation.
Install PostCSS
To build or update your site’s CSS resources, you also need PostCSS to create the final assets. If you need to install it, you must have a recent version of NodeJS installed on your machine so you can use npm, the Node package manager. By default npm installs tools under the directory where you run npm install:
1.1.2 - Create a new site: start with a prepopulated site
Create a new Hugo site by using a clone of the Docsy example site as your starting point.
The simplest way to create a new Docsy site is to use the source of the Docsy example site as starting point. This approach gives you a skeleton structure for your site, with top-level and documentation sections and templates that you can modify as necessary. The example site automatically pulls in the Docsy theme as a Hugo Module, so it’s easy to keep up to date.
If you prefer to create a site from scratch, follow the instructions in Start a site from scratch.
TL;DR: Setup for the impatient expert
At your Unix shell or Windows command line, run the following command:
git clone -b sandbox https://github.com/google/docsy-example.git my-new-site
cd my-new-site
hugo server
The Example Site gives you a good starting point for building your docs site and is
pre-configured to automatically pull in the Docsy theme as a Hugo Module.
There are two different routes to get a local clone of the example site:
If you want to create a local copy only, choose option 1.
If you have a GitHub account and want to create a GitHub repo for your site go for option 2.
Option 1: Using the command line (local copy only)
If you want to use a remote repository other than GitHub (such as GitLab, BitBucket, AWS CodeCommit, Gitea) or if you don’t want a remote repo at all, simply make a local working copy of the example site directly using git clone. As last parameter, give your chosen local repo name (here: my-new-site):
Chose a name for your new repository (e.g. my-new-site) and type it in the Repository name field. You can also add an optional Description.
Click Create repository from template to create your new repository. Congratulations, you just created your remote Github clone which now serves as starting point for your own site!
Make a local copy of your newly created GitHub repository by using git clone, giving your repo’s web URL as last parameter.
Now you can make local edits and test your copied site locally with Hugo.
Preview your site
To build and preview your site locally, switch to the root of your cloned project and use hugo’s server command:
cd my-new-site
hugo server
Preview your site in your browser at: http://localhost:1313.
Thanks to Hugo’s live preview, you can immediately see the effect of changes that you are making to the source files of your local repo.
Use Ctrl + c to stop the Hugo server whenever you like.
See the known issues on MacOS.
1.1.3 - Create a new site: Start a new site from scratch
Create a new Hugo site from scratch with Docsy as a Hugo Module
The simplest approach to creating a Docsy site is copying our example site. However, if you’re an experienced Hugo user or the site structure of our example site doesn’t meet your needs, you may prefer to create a new site from scratch. With this option, you’ll get Docsy look and feel, navigation, and other features, but you’ll need to specify your own site structure.
These instructions give you a minimum file structure for your site project only, so that you build and extend your actual site step by step. The first step is adding the Docsy theme as a Hugo Module to your site. If needed, you can easily update the module to the latest revision from the Docsy GitHub repo.
hugo new site my-new-site
cd my-new-site
hugo mod init github.com/me/my-new-site
hugo mod get github.com/google/docsy@0.2.0-pre
hugo mod get github.com/google/docsy/dependencies@0.2.0-pre
cat >> config.toml <<EOL
[module]
[[module.imports]]
path = "github.com/google/docsy"
[[module.imports]]
path = "github.com/google/docsy/dependencies"
EOL
hugo server
hugo new site my-new-site
cd my-new-site
hugo mod init github.com/me/my-new-site
hugo mod get github.com/google/docsy@0.2.0-pre
hugo mod get github.com/google/docsy/dependencies@0.2.0-pre
(echo [module]^
[[module.imports]]^
path = "github.com/google/docsy"^
[[module.imports]]^
path = "github.com/google/docsy/dependencies")>>config.toml
hugo server
Specifying the Docsy theme as Hugo Module for your minimal site gives you all the theme-y goodness, but you’ll need to specify your own site structure.
Create your new skeleton project
To create a new Hugo site project and then add the Docs theme as a submodule, run the following commands from your project’s root directory.
hugo new site my-new-site
cd my-new-site
This will create a minimal site structure, containing the folders archetypes, content, data, layouts, static, and themes and a configuration file, `config.toml.
Import the Docsy theme module as a dependency of your site
Only sites that are Hugo Modules themselves can import other modules. To turn your site into a Hugo Module, run the following commands in your newly created site directory:
hugo mod init github.com/me/my-new-site
This creates two new files, go.mod for the module definitions and go.sum which holds the checksums for module verification.
Next declare the Docsy theme module as a dependency for your site. You must also declare the submodule dependencies as a second dependency. This submodule pulls in both a workaround for a bug in Go’s module management and the dependencies bootstrap and Font-Awesome.
hugo mod get github.com/google/docsy@0.2.0-pre
hugo mod get github.com/google/docsy/dependencies@0.2.0-pre
These commands add both the docsy theme module and the dependencies submodule to your definition file go.mod.
Add theme module configuration settings
Add the settings in the following snippet at the end of your site configuration file (default: config.toml) and save the file.
By default, your site will be available at http://localhost:1313. When encountering problems, have a look at the known issues on MacOS.
You may get Hugo errors for missing parameters and values when you try to build your site. This is usually because you’re missing default values for some configuration settings that Docsy uses - once you add them your site should build correctly. You can find out how to add configuration in Basic site configuration - we recommend copying the example site configuration even if you’re creating a site from scratch as it provides defaults for many required configuration parameters.
Create a new Docsy site with Docsy as a Git submodule or cloned theme
If you don’t want to use Docsy as a Hugo Module (for example if you do not want to install Go) but still don’t want to copy the theme files into your own repo, you can use Docsy as a Git submodule. Using submodules also lets Hugo use the theme files from Docsy repo, though is more complicated to maintain than the Hugo Modules approach. This is the approach used in older versions of the Docsy example site, and is still supported. If you are using Docsy as a submodule but would like to migrate to Hugo Modules, see our migration guide.
Alternatively if you don’t want Hugo to have to get the theme files from an external repo (for example, if you want to customize and maintain your own copy of the theme directly, or your deployment choice requires you to include a copy of the theme in your repository), you can clone the files directly into your site source.
This guide provides instructions for both these options, along with common prerequisites.
Prerequisites and installation
Install Hugo
You need a recent extended version (we recommend version 0.73.0 or later) of Hugo to do local builds and previews of sites (like this one) that use Docsy. If you install from the release page, make sure to get the extended Hugo version, which supports SCSS; you may need to scroll down the list of releases to see it.
For comprehensive Hugo documentation, see gohugo.io.
If you’ve already installed Hugo, check your version:
hugo version
If the result is v0.73 or earlier, or if you don’t see Extended, you’ll need to install the latest version. You can see a complete list of Linux installation options in Install Hugo. The following shows you how to install Hugo from the release page:
You can install Hugo as an npm module using hugo-bin. This adds hugo-bin to your node_modules folder and adds the dependency to your package.json file. To install the extended version of Hugo:
To build or update your site’s CSS resources, you also need PostCSS to create the final assets. If you need to install it, you must have a recent version of NodeJS installed on your machine so you can use npm, the Node package manager. By default npm installs tools under the directory where you run npm install:
If you don’t want to use a submodules (for example, if you want to customize and maintain your own copy of the theme directly, or your deployment choice requires you to include a copy of the theme in your repository), you can clone the theme into your project’s themes subdirectory.
To clone Docsy into your project’s theme folder, run the following commands from your project’s root directory:
cd themes
git clone https://github.com/google/docsy
If you want to build and/or serve your site locally, you also need to get local copies of the theme’s own submodules:
You may get Hugo errors for missing parameters and values when you try to build your site. This is usually because you’re missing default values for some configuration settings that Docsy uses - once you add them your site should build correctly. You can find out how to add configuration in Basic site configuration - we recommend copying the example site configuration even if you’re creating a site from scratch as it provides defaults for many required configuration parameters.
Change your working directory to the newly created folder:
cd docsy-example
Build and run the container
The docsy-example repository includes a
Dockerfile that you can
use to run your site.
Build the docker image:
docker-compose build
Run the built image:
docker-compose up
Open the address http://localhost:1313 in your web browser to load the
docsy-example homepage. You can now make changes to the source files, those
changes will be live-reloaded in your browser.
Cleanup
To cleanup your system and delete the container image follow the next steps.
Site-wide configuration details and parameters are defined in your project’s config.toml file. These include your chosen Hugo theme (Docsy, of course!), project name, community links, Google Analytics configuration, and Markdown parser parameters. See the examples with comments in config.toml in the example project for how to add this information. We recommend copying this config.toml and editing it even if you’re just using the theme and not copying the entire Docsy example site, as it includes default values for many parameters that you need to set for your site to build correctly.
You may want to remove or customize some defaults of the copied config.toml file straight away:
Internationalization
The copied config.toml file defines content in English, Norwegian and Farsi. You can find out more about how Docsy supports multi-language content in Multi-language support.
If you don’t intend to translate your site, you can remove the language switcher by removing the following lines from config.toml:
[languages.no]
title = "Docsy"
description = "Docsy er operativsystem for skyen"
languageName ="Norsk"
contentDir = "content/no"
time_format_default = "02.01.2006"
time_format_blog = "02.01.2006"
[languages.fa]
title = "اسناد گلدی"
description = "یک نمونه برای پوسته داکسی"
languageName ="فارسی"
contentDir = "content/fa"
time_format_default = "2006.01.02"
time_format_blog = "2006.01.02"
Search
By default, the Docsy example site uses its own Google Custom Search Engine. To disable this site search, delete or comment out the following lines:
# Google Custom Search Engine ID. Remove or comment out to disable search.
gcs_engine_id = "011737558837375720776:fsdu1nryfng"
To use your own Custom Search Engine, replace the value in the gcs_engine_id with the ID of your own search engine. Or choose another search option.
Errors: too many open files or fatal error: pipe failed
By default, MacOS permits a small number of open File Descriptors. For larger sites, or when you’re simultaneously running multiple applications,
you might receive one of the following errors when you run hugo server to preview your site locally:
POSTCSS v7 and earlier:
ERROR 2020/04/14 12:37:16 Error: listen tcp 127.0.0.1:1313: socket: too many open files
POSTCSS v8 and later:
fatal error: pipe failed
Workaround
To temporarily allow more open files:
View your current settings by running:
sudo launchctl limit maxfiles
Increase the limit to 65535 files by running the following commands. If your site has fewer files, you can set choose to set lower soft (65535) and
hard (200000) limits.
If you’re using WSL, ensure that you’re running hugo on a Linux mount of the filesystem, rather than a Windows one, otherwise you may get unexpected errors.
2 - Content and Customization
How to add content to and customize your Docsy site.
2.1 - Adding Content
Add different types of content to your Docsy site.
So you’ve got a new Hugo website with Docsy, now it’s time to add some content! This page tells you how to use the theme to add and structure your site content.
Content root directory
You add content for your site under the content root directory of your Hugo site project - either content/ or a language-specific root like content/en/. The main exception here is static files that you don’t want built into your site: you can find out more about where you add these below in Adding static content. The files in your content root directory are typically grouped in subdirectories corresponding to your site’s sections and templates, which we’ll look at in Content sections and templates.
Hugo builds your site pages using the content files you provide plus any templates provided by your site’s theme. These templates (or “layouts” in Hugo terminology) include things like your page’s headers, footers, navigation, and links to stylesheets: essentially, everything except your page’s specific content. The templates in turn can be made up of partials: little reusable snippets of HTML for page elements like headers, search boxes, and more.
Because most technical documentation sites have different sections for different types of content, the Docsy theme comes with the following templates for top-level site sections that you might need:
docs is for pages in your site’s Documentation section.
It also provides a default “landing page” type of template with the site header and footer, but no left nav, that you can use for any other section. In this site and our example site it’s used for the site home page and the About page.
Each top-level section in your site corresponds to a directory in your site content root. Hugo automatically applies the appropriate template for that section, depending on which folder the content is in. For example, this page is in the docs subdirectory of the site’s content root directory content/en/, so Hugo automatically applies the docs template. You can override this by explicitly specifying a template or content type for a particular page.
If you’ve copied the example site, you already have appropriately named top-level section directories for using Docsy’s templates, each with an index page ( _index.md or index.html) page for users to land on. These top-level sections also appear in the example site’s top-level menu.
Custom sections
If you’ve copied the example site and don’t want to use one of the provided content sections, just delete the appropriate content subdirectory. Similarly, if you want to add a top-level section, just add a new subdirectory, though you’ll need to specify the layout or content type explicitly in the frontmatter of each page if you want to use any existing Docsy template other than the default one. For example, if you create a new directory content/en/amazing and want one or more pages in that custom section to use Docsy’s docs template, you add type: docs to the frontmatter of each page:
---title:"My amazing new section"weight:1type:docsdescription:>A special section with a docs layout.---
Alternatively, create your own page template for your new section in your project’s layouts directory based on one of the existing templates.
You can find out much more about how Hugo page layouts work in Hugo Templates. The rest of this page tells you about how to add content and use each of Docsy’s templates.
Alternative site structure
As noted above, by default your site has a home page (using the _default layout), a docs section under /docs/, a blog section under /blog/ and a community section under /community/. The type of each section (which determines the layout it uses) matches its directory name.
In some cases, you may want to have a different directory structure, but still make use of Docsy’s layouts. A common example is for a “docs site”, where most of the pages (including the home page) use the docs layout, or perhaps you’d rather have a /news/ directory treated with the blog layout.
Since Hugo 0.76, this has become practical without copying layouts to your site, or having to specify type: blog on every single page by making use of target specific cascading front matter.
For example, for the /news/ section, you can specify the following front matter in the index page which will change the type of the section and everything below it to “blog”:
If you want to create a “docs” site, specifying something like the following in the top level _index.md will set all top level sections to be treated as “docs”, except for “news”:
Note the addition of toc_root here. Setting that to true for a section causes it to be treated as a separate part of the site, with its own left hand navigation menu.
An example docs-based site that uses this technique can be found at the mostly docs repo.
Page frontmatter
Each page file in a Hugo site has metadata frontmatter that tells Hugo about the page. You specify page frontmatter in TOML, YAML, or JSON (our example site and this site use YAML). Use the frontmatter to specify the page title, description, creation date, link title, template, menu weighting, and even any resources such as images used by the page. You can see a complete list of possible page frontmatter in Front Matter.
For example, here’s the frontmatter for this page:
---title:"Adding Content"linkTitle:"Adding Content"weight:1description:>Add different types of content to your Docsy site.---
The minimum frontmatter you need to provide is a title: everything else is up to you! However, if you leave out the page weight, your navigation may get a little disorganized. You may also want to include description since Docsy uses that to generate the meta description tag used by search engines. See Search Engine Optimization (SEO) meta tags for details.
Page contents and markup
By default you create pages in a Docsy site as simple Markdown or HTML files with page frontmatter, as described above. Versions of Hugo before 0.60 use BlackFriday as its Markdown parser. From 0.60, Hugo uses Goldmark as its Markdown parser by default.
Tip
If you’ve been using earlier versions of Hugo, you may need to make some small changes to your site to work with the current Markdown parser. In particular, if you cloned an earlier version of our example site, add the following to your config.toml to allow Goldmark to render raw HTML as well as Markdown:
Alternatively, if you want to continue using Blackfriday, you can follow the instructions in the Hugo documentation to change the Markdown parser.
In addition to your marked-up text, you can also use Hugo and Docsy’s shortcodes: reusable chunks of HTML that you can use to quickly build your pages. Find out more about shortcodes in Docsy Shortcodes.
Note
Hugo also supports adding content using other markups using external parsers as helpers. For example, you can add content in RST using rst2html as an external parser (though be aware this does not support all flavors of RST, such as Sphinx RST). Similarly, you can use asciidoctor to parse Asciidoc files, or pandoc for other formats.
External parsers may not be suitable for use with all deployment options, as you’ll need to install the external parser and run Hugo yourself to generate your site (so, for example, you won’t be able to use Netlify’s continuous deployment feature). In addition, adding an external parser may cause performance issues building larger sites.
Working with links
Hugo lets you specify links using normal Markdown syntax, though remember that you need to specify links relative to your site’s root URL, and that relative URLs are left unchanged by Hugo in your site’s generated HTML.
Alternatively you can use Hugo’s helper ref and relref shortcodes for creating internal links that resolve to the correct URL. However, be aware this means your links will not appear as links at all if a user views your page outside your generated site, for example using the rendered Markdown feature in GitHub’s web UI.
You can find (or add!) tips and gotchas for working with Hugo links in Hugo Tips.
Content style
We don’t mandate any particular style for your page contents. However, if you’d like some guidance on how to write and format clear, concise technical documentation, we recommend the Google Developer Documentation Style Guide, particularly the Style Guide Highlights.
Page bundles
You can create site pages as standalone files in their section or subsection directory, or as folders where the content is in the folder’s index page. Creating a folder for your page lets you bundle images and other resources together with the content.
You can see examples of both approaches in this and our example site. For example, the source for this page is just a standalone file /content/en/docs/adding-content.md. However the source for Docsy Shortcodes in this site lives in /content/en/docs/adding-content/shortcodes/index.md, with the image resource used by the page in the same /shortcodes/ directory. In Hugo terminology, this is called a leaf bundle because it’s a folder containing all the data for a single site page without any child pages (and uses index.md without an underscore).
You can find out much more about managing resources with Hugo bundles in Page Bundles.
Adding docs and blog posts
The template you’ll probably use most often is the docs template (as used in this page) or the very similar blog template. Both these templates include:
a left nav
GitHub links (populated from your site config) for readers to edit the page or create issues
a page menu
as well as the common header and footer used by all your site’s pages. Which template is applied depends on whether you’ve added the content to the blog or docs content directory. You can find out more about how the nav and page menu are created in Navigation and Search.
Organizing your documentation
While Docsy’s top-level sections let you create site sections for different types of content, you may also want to organize your docs content within your docs section. For example, this site’s docs section directory has multiple subdirectories for Getting Started, Content and Customization, and so on. Each subdirectory has an _index.md (it could also be an _index.html), which acts as a section index page and tells Hugo that the relevant directory is a subsection of your docs.
Docsy’s docs layout gives you a left nav pane with an autogenerated nested menu based on your docs file structure. Each standalone page or subsection _index.md or _index.html page in the docs/ directory gets a top level menu item, using the link name and weight metadata from the page or index.
To add docs to a subsection, just add your page files to the relevant subdirectory. Any pages that you add to a subsection in addition to the subsection index page will appear in a submenu (look to the left to see one in action!), again ordered by page weight. Find out more about adding Docsy’s navigation metadata in Navigation and Search
If you’ve copied the example site, you’ll already have some suggested subdirectories in your docs directory, with guidance for what types of content to put in them and some example Markdown pages. You can find out more about organizing your content with Docsy in Organizing Your Content.
Docs section landing pages
By default a docs section landing page (the _index.md or _index.html in the section directory) uses a layout that adds a formatted list of links to the pages in the section, with their frontmatter descriptions. The Content and Customization landing page in this site is a good example.
To display a simple bulleted list of links to the section’s pages instead, specify simple_list: true in the landing page’s frontmatter:
---
title: "Simple List Page"
simple_list: true
weight: 20
---
To display no links at all, specify no_list: true in the landing page’s frontmatter:
---
title: "No List Page"
no_list: true
weight: 20
---
Organizing your blog posts
Docsy’s blog layout also gives you a left nav menu (like the docs layout), and a list-type index page for your blog that’s applied to /blog/_index.md and automatically displays snippets of all your recent posts in reverse chronological order.
To create different blog categories to organize your posts, create subfolders in blog/. For instance, in our example site we have news and releases. Each category needs to have its own _index.md or _index.html landing page file specifying the category title for it to appear properly in the left nav and top-level blog landing page. Here’s the index page for releases:
---
title: "New Releases"
linkTitle: "Releases"
weight: 20
---
To add author and date information to blog posts, add them to the page frontmatter:
---
date: 2018-10-06
title: "Easy documentation with Docsy"
linkTitle: "Announcing Docsy"
description: "The Docsy Hugo theme lets project maintainers and contributors focus on content, not on reinventing a website infrastructure from scratch"

If you’ve copied the example site and you don’t want a blog section, or want to link to an external blog instead, just delete the blog subdirectory.
Working with top-level landing pages.
Docsy’s default page template has no left nav and is useful for creating a home page for your site or other “landing” type pages.
Customizing the example site pages
If you’ve copied the example site, you already have a simple site landing page in content/en/_index.html. This is made up of Docsy’s provided Hugo shortcode page blocks.
To customize the large landing image, which is in a cover block, replace the content/en/featured-background.jpg file in your project with your own image (it can be called whatever you like as long as it has background in the file name). You can remove or add as many blocks as you like, as well as adding your own custom content.
The example site also has an About page in content/en/about/_index.html using the same Docsy template. Again, this is made up of page blocks, including another background image in content/en/about/featured-background.jpg. As with the site landing page, you can replace the image, remove or add blocks, or just add your own content.
Building your own landing pages
If you’ve just used the theme, you can still use all Docsy’s provided page blocks (or any other content you want) to build your own landing pages in the same file locations.
Adding a community page
The community landing page template has boilerplate content that’s automatically filled in with the project name and community links specified in config.toml, providing your users with quick links to resources that help them get involved in your project. The same links are also added by default to your site footer.
[params.links]# End user relevant links. These will show up on left side of footer and in the community page if you have one.[[params.links.user]]name="User mailing list"url="https://example.org/mail"icon="fa fa-envelope"desc="Discussion and help from your fellow users"[[params.links.user]]name="Twitter"url="https://example.org/twitter"icon="fab fa-twitter"desc="Follow us on Twitter to get the latest news!"[[params.links.user]]name="Stack Overflow"url="https://example.org/stack"icon="fab fa-stack-overflow"desc="Practical questions and curated answers"# Developer relevant links. These will show up on right side of footer and in the community page if you have one.[[params.links.developer]]name="GitHub"url="https://github.com/google/docsy"icon="fab fa-github"desc="Development takes place here!"[[params.links.developer]]name="Slack"url="https://example.org/slack"icon="fab fa-slack"desc="Chat with other project developers"[[params.links.developer]]name="Developer mailing list"url="https://example.org/mail"icon="fa fa-envelope"desc="Discuss development issues around the project"
If you’re creating your own site and want to add a page using this template, add a /community/_index.md file in your content root directory. If you’ve copied the example site and don’t want a community page, just delete the /content/en/community/ directory in your project repo.
Adding static content
You may want to serve some non-Hugo-built content along with your site: for example, if you have generated reference docs using Doxygen, Javadoc, or other doc generation tools.
To add static content to be served “as-is”, just add the content as a folder and/or files in your site’s static directory. When your site is deployed, content in this directory is served at the site root path. So, for example, if you have added content at /static/reference/cpp/, users can access that content at http://{server-url}/reference/cpp/ and you can link to pages in this directory from other pages at /reference/cpp/{file name}.
You can also use this directory for other files used by your project, including image files. You can find out more about serving static files, including configuring multiple directories for static content, in Static Files.
RSS feeds
Hugo will, by default, create an RSS feed for the home page and any section. For the main RSS feed you can control which sections to include by setting a site param in your config.toml. This is the default configuration:
rss_sections=["blog"]
To disable all RSS feeds, add the following to your config.toml:
disableKinds=["RSS"]
Note
If you have enabled our print feature or otherwise specified section-level output formats in config.toml, make sure that "RSS" is listed as an output format, otherwise you won’t get section-level RSS feeds (and your blog section won’t get a nice orange RSS button). Your config.toml specification overrides the Hugo default output formats for sections, which are HTML and RSS.
[outputs]section=["HTML","RSS","print"]
Sitemap
Hugo creates a sitemap.xml file for your generated site by default: for example, here’s the sitemap for this site.
You can configure the frequency with which your sitemap is updated, your sitemap filename, and the default page priority in your config.toml:
Customize colors, fonts, code highlighting, and more for your site.
By default, a site using Docsy has the theme’s default fonts, colors, and general look and feel. However, if you want your own color scheme (and you probably will!) you can very easily override the theme defaults with your own project-specific values - Hugo will look in your project files first when looking for information to build your site. And because Docsy uses Bootstrap 4 and SCSS for styling, you can override just single values (such as project colors and fonts) in its special SCSS project variables file, or do more serious customization by creating your own styles.
Docsy also provides options for styling your code blocks, using either Chroma or Prism for highlighting.
Project style files
To customize your project’s look and feel, create your own version of either or both of the following
Docsy placeholder files (note the _project.scss suffixes):
assets/scss/_styles_project.scss is where you can add your own custom SCSS styles, including overriding any of the styles in Docsy’s theme SCSS files.
Tip
PostCSS (autoprefixing of CSS browser-prefixes) is not enabled when running in server mode (it is a little slow), so Chrome is the recommended choice for development.
Site colors
To easily customize your site’s colors, add SCSS variable overrides to
assets/scss/_variables_project.scss. A simple example changing the primary and
secondary color to two shades of purple:
$primary:#390040;$secondary:#A23B72;
The theme has features such as rounded corners and gradient backgrounds enabled by default. These can also be toggled in your project variables file:
The theme uses Open Sans as its primary font. To disable Google Fonts and use a system font, set this SCSS variable in assets/scss/_variables_project.scss:
Note that if you decide to go with a font with different weights (in the built-in configuration this is 300 (light), 400 (medium) and 700 (bold)), you also need to adjust the weight related variables, i.e. variables starting with $font-weight-.
CSS utilities
For documentation of available CSS utility classes, see the Bootstrap Documentation. This theme adds very little on its own in this area. However, we have added some color state CSS classes that can be useful in a dynamic context:
.-bg-<color>
.-text-<color>
You can use these classes, for example, to style your text in an appropriate color when you don’t know if the primary color is dark or light, to ensure proper color contrast. They are also useful when you receive the color code as a shortcode parameter.
The value of <color> can be any of the color names, primary, white, dark, warning, light, success, 300, blue, orange etc.
When you use .-bg-<color>, the text colors will be adjusted to get proper contrast:
With Hugo version 0.60 and higher, you can choose from a range of code block highlight and colour styles using Chroma that are applied to your fenced code blocks by default. If you copied a recent config.toml your site uses Tango (like this site), otherwise the Hugo default is Monokai. You can switch to any of the available Chroma styles (including our Docsy default Tango) using your config.toml:
[markup][markup.goldmark][markup.goldmark.renderer]unsafe=true[markup.highlight]# See a complete list of available styles at https://xyproto.github.io/splash/docs/all.htmlstyle="tango"
By default code highlighting styles are not applied to code blocks without a specified language, instead you get Docsy’s default style of grey with black text. If you would like the code highlighting style to apply to all code blocks, even without a language, uncomment or add the following line under [markup.highlight] in your config.toml.
# Uncomment if you want your chosen highlight style used for code blocks without a specified languageguessSyntax="true"
You can find out more about code highlighting in Hugo with Chroma in Syntax Highlighting.
Code highlighting with Prism
Optionally, you can enable Prism syntax highlighting in your config.toml:
# Enable syntax highlighting and copy buttons on code blocks with Prismprism_syntax_highlighting=true
When this option is enabled your site uses Prism instead of Chroma for code block highlighting.
Prism is a popular open source syntax highlighter which supports over 200 languages and various plugins.
Docsy includes JavaScript and CSS files for a basic Prism configuration, which supports:
Code blocks styled with the Prism Default theme
Copy to clipboard buttons on code blocks
Syntax highlighting for a number of common languages, as specified in the following Prism download link:
By default Prism code highlighting styles are not applied to code blocks without a specified language, instead you get Docsy’s default style of grey with black text. To apply Prism styling to code blocks with no language or a language not supported by Prism, specify none as the language after your triple backticks.
Extending Prism for additional languages or plugins
If the included Prism configuration is not sufficient for your requirements, and you want to use additional languages or plugins you can replace the included files with your own.
Replace the included Prism JS and CSS with the files you downloaded:
Copy the Javascript file to static/js/prism.js
Copy the CSS file to static/css/prism.css
Navbar
For pages containing a blocks/cover shortcode, like most homepages, the
navbar is translucent as long as the hero image hasn’t scrolled up past the
navbar. For an example, see the About Docsy page. This initial translucent
setting ensures that the hero image is maximally visible.
After the hero image has scrolled past the navbar, the navbar’s (opaque)
background color is set – usually to the site’s primary color.
The text of navbar entries can be difficult to read with some hero images. In
these cases, you can disable navbar translucency by setting the
params.ui.navbar_translucent_over_cover_disable option to true in your
site’s configuration file.
Customizing templates
Add code to head or before body end
If you need to add some code (CSS import, cookie consent, or similar) to the head section on every page, add the head-end.html partial to your project:
layouts/partials/hooks/head-end.html
And add the code you need in that file. Your partial code is automatically included just before the end of the theme partial head.html. The theme version of head-end.html is empty.
Similarly, if you want to add some code right before the body end, create your own version of the following file:
layouts/partials/hooks/body-end.html
Any code in this file is included automatically at the end of the theme partial scripts.html.
Both head.html and scripts.html are then used to build Docsy’s base page layout, which is used by all the other page templates:
Customize site navigation and search for your Docsy site.
Top-level menu
The top level menu (the one that appears in the top navigation bar for the entire site) uses your site’s main menu. All Hugo sites have a main menu array of menu entries, accessible via the .Site.Menus site variable and populatable via page front matter or your site’s config.toml.
To add a page or section to this menu, add it to the site’s main menu in either config.toml or in the destination page’s front matter (in _index.md or _index.html for a section, as that’s the section landing page). For example, here’s how we added the Documentation section landing page to the main menu in this site:
---title:"Welcome to Docsy"linkTitle:"Documentation"menu:main:weight:20pre:<i class='fas fa-book'></i>---
The menu is ordered from left to right by page weight. So, for example, a section index or page with weight: 30 would appear after the Documentation section in the menu, while one with weight: 10 would appear before it.
If you want to add a link to an external site to this menu, add it in config.toml, specifying the weight.
As described in the Hugo docs, you can add icons to the top-level menu by using the pre and/or post parameter for main menu items defined in your site’s config.toml or via page front matter. For example, the following configuration adds the GitHub icon to the GitHub menu item, and a New! alert to indicate that this is a new addition to the menu.
If you configure more than one language in config.toml, the Docsy theme adds a language selector drop down to the top-level menu. Selecting a language takes the user to the translated version of the current page, or the home page for the given language.
The section menu, as shown in the left side of the docs section, is automatically built from the content tree. Like the top-level menu, it is ordered by page or section index weight (or by page creation date if weight is not set), with the page or index’s Title, or linkTitle if different, as its link title in the menu. If a section subfolder has pages other than _index.md or _index.html, those pages will appear as a submenu, again ordered by weight. For example, here’s the metadata for this page showing its weight and title:
---title:"Navigation and Search"linkTitle:"Navigation and Search"date:2017-01-05weight:3description:>Customize site navigation and search for your Docsy site.---
To hide a page or section from the left navigation menu, set toc_hide: true in the front matter.
To hide a page from the section summary on a docs section landing page, set hide_summary: true in the front matter. If you want to hide a page from both the TOC menu and the section summary list, you need to set both toc_hide and hide_summary to true in the front matter.
---title:"My Hidden Page"weight:99toc_hide:truehide_summary:truedescription:>Page hidden from both the TOC menu and the section summary list.---
Section menu options
By default, the section menu shows the current section fully expanded all the way down. This may make the left nav too long and difficult to scan for bigger sites. Try setting site parameter ui.sidebar_menu_compact = true in config.toml.
With the compact menu (.ui.sidebar_menu_compact = true), only the current page’s ancestors, siblings and direct descendants are shown. You can use the optional parameter .ui.ul_show to set a desired menu depth to always be visible. For example, with .ui.ul_show = 1 the first menu level is always displayed.
As well as the completely expanded and compact menu options, you can also create a foldable menu by setting the site parameter ui.sidebar_menu_foldable = true in config.toml. The foldable menu lets users expand and collapse menu sections by toggling arrow icons beside the section parents in the menu.
On large sites (default: > 2000 pages) the section menu is not generated for each page, but cached for the whole section. The HTML classes for marking the active menu item (and menu path) are then set using JS. You can adjust the limit for activating the cached section menu with the optional parameter .ui.sidebar_cache_limit.
Add icons to the section menu
You can add icons to the section menu in the sidebar by setting the icon parameter in the page front matter (e.g. icon: fas fa-tools).
You can find a complete list of icons to use in the FontAwesome documentation. Docsy includes the free FontAwesome icons by default.
Out of the box, if you want to use icons, you should define icons for all items on the same menu level in order to ensure an appropriate look. If the icons are used in a different way, individual CSS adjustments are likely necessary.
Add manual links to the section menu
By default the section menu is entirely generated from your section’s pages. If you want to add a manual link to this menu, such as a link to an external site or a page in a different section of your site, you can do this by creating a placeholder page file in the doc hierarchy with the appropriate weight and some special parameters in its metadata (frontmatter) to specify the link details.
To create a placeholder page, create a page file as usual in the directory where you want the link to show up in the menu, and add a manualLink parameter to its metadata. If a page has manualLink in its metadata, Docsy generates a link for it in the section menu for this page and in the section index (the list of the child pages of a section on a landing page - see description in the Docsy docs), but the link destination is replaced by the value of manualLink. The link text is the title (or linkTitle if set) of your placeholder page. You can optionally also set the title attribute of the link with the parameter manualLinkTitle and a link target with manualLinkTarget - for example if you want an external link to open in a new tab you can set the link target to _blank. Docsy automatically adds rel=noopener to links that open new tabs as a security best practice.
You can also use manualLink to add an additional cross reference to another existing page of your site. For internal links you can choose to use the parameter manualLinkRelref instead of manualLink to use the built-in Hugo function relref. If relref can’t find a unique page in your site, Hugo throws a error message.
Note
Although all generated menu and landing page links based on your placeholder file are set according to the parameters manualLink or manualLinkRelref, Hugo still generates a regular HTML site page for the file, albeit one with no generated links to it. To avoid confusion if users accidentally land on a generated placeholder page, we recommend specifying the URL for the external link in the normal content and / or page description of the page.
Breadcrumb navigation
Breadcrumb navigation is enabled by default. To disable breadcrumb navigation, set site param ui.breadcrumb_disable = true in config.toml.
Site search options
Docsy offers multiple options that let your readers search your site content, so you can pick one that suits your needs. You can choose from:
Google Custom Search Engine (GCSE), the default option, which uses Google’s index of your public site to generate a search results page.
Algolia DocSearch, which uses Algolia’s indexing and search mechanism, and provides an organized dropdown of search results when your readers use the search box. Algolia DocSearch is free for public documentation sites.
Local search with Lunr, which uses Javascript to index and search your site without the need to connect to external services. This option doesn’t require your site to be public.
If you enable any of these search options in your config.toml, a search box displays in the right of your top navigation bar. By default a search box also displays at the top of the section menu in the left navigation pane, which you can disable if you prefer, or if you’re using a search option that only works with the top search box.
Be aware that if you accidentally enable more than one search option in your config.toml you may get unexpected results (for example, if you have added the .js for Algolia DocSearch, you’ll get Algolia results if you enable GCSE search but forget to disable Algolia search).
Disabling the sidebar search box
By default, the search box appears in both the top navigation bar and at the top of the sidebar left navigation pane. If you don’t want the sidebar search box, set sidebar_search_disable to true in config.toml:
sidebar_search_disable = true
Configure search with a Google Custom Search Engine
By default Docsy uses a Google Custom Search Engine (GCSE) to search your site. To enable this feature, you’ll first need to make sure that you have built and deployed a production version of your site, as otherwise your site won’t be crawled and indexed.
Setting up site search
Create a Google Custom Search Engine for your deployed site by clicking New search engine on the Custom Search page and following the instructions. Make a note of the ID for your new search engine.
Add any further configuration you want to your search engine using the Edit search engine options. In particular you may want to do the following:
Select Look and feel. Change from the default Overlay layout to Results only, as this option means your search results are embedded in your search page rather than appearing in a separate box. Click Save to save your changes.
Edit the default result link behavior so that search results from your site don’t open in a new tab. To do this, select Search Features - Advanced - Websearch Settings. In the Link Target field, type “_parent”. Click Save to save your changes.
Once you have your search engine set up, you can add the feature to your site:
Ensure you have a Markdown file in content/en/search.md (and one per other languages if needed) to display your search results. It only needs a title and layout: search, as in the following example:
---
title: Search Results
layout: search
---
Add your Google Custom Search Engine ID to the site params in config.toml. You can add different values per language if needed.
# Google Custom Search Engine ID. Remove or comment out to disable search.
gcs_engine_id = "011737558837375720776:fsdu1nryfng"
Disabling GCSE search
If you don’t specify a Google Custom Search Engine ID for your project and haven’t enabled any other search options, the search box won’t appear in your site. If you’re using the default config.toml from the example site and want to disable search, just comment out or remove the relevant line.
Configure Algolia DocSearch
As an alternative to GCSE, you can use Algolia DocSearch with this theme. Algolia DocSearch is free for public documentation sites.
Remove or comment out any GCSE ID in config.toml and ensure local search is set to false as you can only have one type of search enabled. See Disabling GCSE search.
Disable the sidebar search in config.toml as this is not currently supported for Algolia DocSearch. See Disabling the sidebar search box.
Add the JavaScript code provided to you by Algolia to the head and body of every page on your site. See Add code to head or before body end for details.
Update the inputSelector field in the body end Javascript with the appropriate CSS selector (e.g. .td-search-input to use the default CSS from this theme).
When you’ve completed these steps the Algolia search should be enabled on your site. Search results are displayed as a drop-down under the search box, so you don’t need to add any search results page.
Configure local search with Lunr
Lunr is a Javascript-based search option that lets you index your site and make it searchable without the need for external, server-side search services. This is a good option particularly for smaller or non-public sites.
To add Lunr search to your Docsy site:
Enable local search in config.toml.
# Enable local search
offlineSearch = true
Remove or comment out any GCSE ID in config.toml and ensure Algolia DocSearch is set to false, as you can only have one type of search enabled. See Disabling GCSE search.
Once you’ve completed these steps, local search is enabled for your site and results appear in a drop down when you use the search box.
Tip
If you’re testing this locally using Hugo’s local server functionality, you need to build your offline-search-index.xxx.json file first by running hugo. If you have the Hugo server running while you build offline-search-index.xxx.json, you may need to stop the server and restart it in order to see your search results.
Changing the summary length of the local search results
You can customize the summary length by setting offlineSearchSummaryLength in config.toml.
To exclude pages from local search results, add exclude_search: true to the the frontmatter of each page:
---title:"Index"weight:10exclude_search:true---
2.4 - Doc Versioning
Customize navigation and banners for multiple versions of your docs.
Depending on your project’s releases and versioning, you may want to let your
users access previous versions of your documentation. How you deploy the
previous versions is up to you. This page describes the Docsy features that you
can use to provide navigation between the various versions of your docs and
to display an information banner on the archived sites.
Adding a version drop-down menu
If you add some [params.versions] in config.toml, the Docsy theme adds a
version selector drop down to the top-level menu. You specify a URL and a name
for each version you would like to add to the menu, as in the following example:
# Add your release versions here
[[params.versions]]
version = "master"
url = "https://master.kubeflow.org"
[[params.versions]]
version = "v0.2"
url = "https://v0-2.kubeflow.org"
[[params.versions]]
version = "v0.3"
url = "https://v0-3.kubeflow.org"
Remember to add your current version so that users can navigate back!
The default title for the version drop-down menu is Releases. To change the
title, change the version_menu parameter in config.toml:
If you create archived snapshots for older versions of your docs, you can add a
note at the top of every page in the archived docs to let readers know that
they’re seeing an unmaintained snapshot and give them a link to the latest
version.
For example, see the archived docs for
Kubeflow v0.6:
Figure 1. The banner on the archived docs for Kubeflow v0.6
To add the banner to your doc site, make the following changes in your
config.toml file:
Set the archived_version parameter to true:
archived_version = true
Set the version parameter to the version of the archived doc set. For
example, if the archived docs are for version 0.1:
version = "0.1"
Make sure that url_latest_version contains the URL of the website that you
want to point readers to. In most cases, this should be the URL of the latest
version of your docs:
Use Docsy’s Hugo shortcodes to quickly build site pages.
Rather than writing all your site pages from scratch, Hugo lets you define and use shortcodes. These are reusable snippets of content that you can include in your pages, often using HTML to create effects that are difficult or impossible to do in simple Markdown. Shortcodes can also have parameters that let you, for example, add your own text to a fancy shortcode text box. As well as Hugo’s built-in shortcodes, Docsy provides some shortcodes of its own to help you build your pages.
Shortcode blocks
The theme comes with a set of custom Page Block shortcodes that can be used to compose landing pages, about pages, and similar.
These blocks share some common parameters:
height
A pre-defined height of the block container. One of min, med, max, full, or auto. Setting it to full will fill the Viewport Height, which can be useful for landing pages.
color
The block will be assigned a color from the theme palette if not provided, but you can set your own if needed. You can use all of Bootstrap’s color names, theme color names or a grayscale shade. Some examples would be primary, white, dark, warning, light, success, 300, blue, orange. This will become the background color of the block, but text colors will adapt to get proper contrast.
blocks/cover
The blocks/cover shortcode creates a landing page type of block that fills the top of the page.
{{<blocks/covertitle="Welcome!"image_anchor="center"height="full"color="primary">}}
<divclass="mx-auto"><aclass="btn btn-lg btn-primary mr-3 mb-4"href="{{< relref "/docs">}}">
Learn More <iclass="fas fa-arrow-alt-circle-right ml-2"></i></a><aclass="btn btn-lg btn-secondary mr-3 mb-4"href="https://example.org"> Download <iclass="fab fa-github ml-2 "></i></a><pclass="lead mt-5">This program is now available in <ahref="#">AppStore!</a></p><divclass="mx-auto mt-5"> {{<blocks/link-downcolor="info">}}
</div></div>{{< /blocks/cover >}}
Note that the relevant shortcode parameters above will have sensible defaults, but is included here for completeness.
Hugo Tip
Using the bracket styled shortcode delimiter, >}}, tells Hugo that the inner content is HTML/plain text and needs no further processing. Changing the delimiter to %}} means Hugo will treat the content as Markdown. You can use both styles in your pages.
Parameter
Default
Description
title
The main display title for the block.
image_anchor
height
See above.
color
See above.
byline
Byline text on featured image.
To set the background image, place an image with the word “background” in the name in the page’s Page Bundle. For example, in our the example site the background image in the home page’s cover block is featured-background.jpg, in the same directory.
Tip
If you also include the word featured in the image name, e.g. my-featured-background.jpg, it will also be used as the Twitter Card image when shared.
The blocks/lead block shortcode is a simple lead/title block with centred text and an arrow down pointing to the next section.
{{%blocks/leadcolor="dark"%}}TechOS is the OS of the future.
Runs on **bare metal** in the **cloud**!
{{%/blocks/lead%}}

The pageinfo shortcode creates a text box that you can use to add banner information for a page: for example, letting users know that the page contains placeholder content, that the content is deprecated, or that it documents a beta feature.
{{%pageinfocolor="primary"%}}This is placeholder content.
{{%/pageinfo%}}
Renders to:
This is placeholder content
Parameter
Default
Description
color
primary
One of the theme colors, eg primary, info, warning etc.
imgproc
The imgproc shortcode finds an image in the current Page Bundle and scales it given a set of processing instructions.
{{<imgprocspruceFill"400x450">}}Norway Spruce Picea abies shoot with foliage buds.
{{</imgproc>}}
Norway Spruce Picea abies shoot with foliage buds.

The example above has also a byline with photo attribution added. When using illustrations with a free license from WikiMedia and similar, you will in most situations need a way to attribute the author or licensor. You can add metadata to your page resources in the page front matter. The byline param is used by convention in this theme:
resources:- src:"**spruce*.jpg"params:byline:"Photo: Bjørn Erik Pedersen / CC-BY-SA"
Parameter
Description
1
The image filename or enough of it to identify it (we do Glob matching)
The swaggerui shortcode can be placed anywhere inside a page with the swagger layout; it renders Swagger UI using any OpenAPI YAML or JSON file as source. This can be hosted anywhere you like, for example in your site’s root /static folder.
---title:"Pet Store API"type:swaggerweight:1description:Reference for the Pet Store API---{{< swaggerui src="/openapi/petstore.yaml" >}}
You can customize Swagger UI’s look and feel by overriding Swagger’s CSS or by editing and compiling a Swagger UI dist yourself and replace themes/docsy/static/css/swagger-ui.css.
If true the shortcode tries to calculate the needed height for the embedded content using JavaScript, as described here: https://stackoverflow.com/a/14618068. This is only possible if the embedded content is on the same domain. Note that even if the embedded content is on the same domain, it depends on the structure of the content if the height can be calculated correctly.
style
min-height:98vh; border:none;
CSS styles for the iframe. min-height:98vh; is a backup if tryautoheight doesn’t work. border:none; removes the border from the iframe - this is useful if you want the embedded content to look more like internal content from your page.
sandbox
false
You can switch the sandbox completely on by setting sandbox = true or allow specific functionality with the common values for the iframe parameter sandbox defined in the HTML standard.
There are several tools you can use to check if a website can be embedded via iframe - e.g.: https://gf.dev/x-frame-options-test. Be aware that when this test says “Couldn’t find the X-Frame-Options header
in the response headers.” you CAN embed it, but when the test says “Great! X-Frame-Options header was found in the HTTP response headers as highlighted below.”, you CANNOT - unless it has been explicitly enabled for your site.
Tabbed panes
Sometimes it’s very useful to have tabbed panes when authoring content. One common use-case is to show multiple syntax highlighted code blocks that showcase the same problem, and how to solve it in different programming languages. As an example, the table below shows the language-specific variants of the famous Hello world! program one usually writes first when learning a new programming language from scratch:
The Docsy template provides two shortcodes tabpane and tab that let you easily create tabbed panes. To see how to use them, have a look at the following code block, which renders to a pane with three tabs:
{{<tabpane>}}{{<tabheader="English">}} Welcome!
{{</tab>}}{{<tabheader="German">}} Herzlich willkommen!
{{</tab>}}{{<tabheader="Swahili">}} Karibu sana!
{{</tab>}}{{</tabpane>}}
This code translates to the tabbed pane below, showing a Welcome! greeting in English, German or Swahili:
Tabbed panes are implemented using two shortcodes:
The tabpane shortcode, which is the container element for the tabs. This shortcode can optionally hold the named parameters lang and/or highlight. The values of these optional parameters are passed on as second LANG and third OPTIONS arguments to Hugo’s built-in highlight function which is used to render the code blocks of the individual tabs. In case the header text of the tab equals the language used in the tab’s code block (as in the first tabbed pane example above), you may specify langEqualsHeader=true in the surrounding tabpane shortcode. Then, the header text of the individual tab is automatically set as language parameter of the respective tab.
The various tab shortcodes which actually represent the tabs you would like to show. We recommend specifying the named parameter header for each text in order to set the header text of each tab. If needed, you can additionally specify the named parameters lang and highlight for each tab. This allows you to overwrite the settings given in the parent tabpane shortcode. If the language is neither specified in the tabpane nor in the tabshortcode, it defaults to Hugo’s site variable .Site.Language.Lang.
Card panes
When authoring content, it’s sometimes very useful to put similar text blocks or code fragments on card like elements, which can be optionally presented side by side. Let’s showcase this feature with the following sample card group which shows the first four Presidents of the United States:
George Washington
*1732 †1799
President: 1789 – 1797
John Adams
* 1735 † 1826
President: 1797 – 1801
Thomas Jefferson
* 1743 † 1826
President: 1801 – 1809
James Madison
* 1751 † 1836
President: 1809 – 1817
Docsy supports creating such card panes via different shortcodes:
The cardpane shortcode which is the container element for the various cards to be presented.
The card shortcodes, with each shortcode representing an individual card. While cards are often presented inside a card group, a single card may stand on its own, too. A card shortcode can hold text, images or any other arbitrary kind of markdown or HTML markup as content. If your content is programming code, you are advised to make use of the card-code shortcode, a special kind of card with code-highlighting and other optional features like line numbers, highlighting of certain lines, ….
Shortcode card (for text, images, …)
As stated above, a card is coded using one of the shortcode card or card-code.
If your content is any kind of text other than programming code, use the universal cardshortcode. The following code sample demonstrates how to code a card element:
{{<cardheader="**Imagine**"title="Artist and songwriter: John Lennon"subtitle="Co-writer: Yoko Ono"footer="![SignatureJohnLennon](https://server.tld/…/signature.png \"Signature John Lennon\")">>}}Imagine there's no heaven, It's easy if you try<br/>No hell below us, above us only sky<br/>Imagine all the people living for today…
…
{{</card>}}
This code translates to the left card shown below, showing the lyrics of John Lennon’s famous song Imagine. A second explanatory card element to the right indicates and explains the individual components of a card:
Imagine
Artist and songwriter: John Lennon
Co-writer: Yoko Ono
Imagine there’s no heaven, It’s easy if you try No hell below us, above us only sky Imagine all the people living for today…
Imagine there’s no countries, it isn’t hard to do Nothing to kill or die for, and no religion too Imagine all the people living life in peace…
Imagine no possessions, I wonder if you can No need for greed or hunger - a brotherhood of man Imagine all the people sharing all the world…
You may say I’m a dreamer, but I’m not the only one I hope someday you’ll join us and the world will live as one
Header: specified via named parameter Header
Card title: specified via named parameter title
Card subtitle: specified via named parameter subtitle
Content: inner content of the shortcode, this may be formatted text, images, videos, … . If the extension of your page file equals .md, markdown format is expected, otherwise, your content will be treated as plain HTML.
While the main content of the card is taken from the inner markup of the card shortcode, the optional elements footer, header, title, and subtitle are all specified as named parameters of the shortcode.
Shortcode card-code (for programming code)
In case you want to display programming code on your card, a special shortcode card-code is provided for this purpose. The following sample demonstrates how to code a card element with the famous Hello world!application coded in C:
The card-code shortcode can optionally hold the named parameters lang and/or highlight. The values of these optional parameters are passed on as second LANG and third OPTIONS arguments to Hugo’s built-in highlight function which is used to render the code block presented on the card.
Card groups
Displaying two ore more cards side by side can be easily achieved by putting them between the opening and closing elements of a cardpane shortcode.
The general markup of a card group resembles closely the markup of a tabbed pane:
Contrary to tabs, cards are presented side by side, however. This is especially useful it you want to compare different programming techniques (traditional vs. modern) on two cards, like demonstrated in the example above:
Java 5
File[] hiddenFiles = new File("directory_name")
.listFiles(new FileFilter() {
public boolean accept(File file) {
return file.isHidden();
}
});
Java 8, Lambda expression
File[] hiddenFiles = new File("directory_name")
.listFiles(File::isHidden);
2.6 - Logos and Images
Add and customize logos, icons, and images in your project.
Add your logo
Add your project logo as assets/icons/logo.svg in your project. This overrides the default Docsy logo in the theme. If you don’t want a project logo, set navbar_logo to false (or delete the variable) in your config.toml:
navbar_logo = false
If you decide at a later stage that you’d like to add a logo to your navbar, you can set the parameter to true:
navbar_logo = true
Tip
Your logo is included in the default Docsy navbar as an inline SVG with the following CSS styling (from _nav.scss):
To ensure your logo displays correctly, you may want to resize it, ensure it doesn’t have height and width attributes so that its size is fully responsive, or override the default styling with your own CSS.
Add your favicons
The easiest way to do this is to create a set of favicons via http://cthedot.de/icongen (which lets you create a huge range of icon sizes and options from a single image) and/or https://favicon.io, and put them in your site project’s static/favicons directory. This will override the default favicons from the theme.
Note that https://favicon.io doesn’t create as wide a range of sizes as Icongen but does let you quickly create favicons from text: if you want to create text favicons you can use this site to generate them, then use Icongen to create more sizes (if necessary) from your generated .png file.
If you have special favicon requirements, you can create your own layouts/partials/favicons.html with your links.
Add images
Landing pages
Docsy’s blocks/cover shortcode make it easy to add large cover images to your landing pages. The shortcode looks for an image with the word “background” in the name inside the landing page’s Page Bundle - so, for example, if you’ve copied the example site, the landing page image in content/en/_index.html is content/en/featured-background.jpg.
You specify the preferred display height of a cover block container (and hence its image) using the block’s height parameter. For a full viewport height, use full:
{{<blocks/covertitle="Welcome to the Docsy Example Project!"image_anchor="top"height="full"color="orange">}}
...
{{< /blocks/cover >}}
For a shorter image, as in the example site’s About page, use one of min, med, max or auto (the actual height of the image):
{{<blocks/covertitle="About the Docsy Example"image_anchor="bottom"height="min">}}
...
{{< /blocks/cover >}}
Other pages
To add inline images to other pages, use the imgproc shortcode. Alternatively, if you prefer, just use regular Markdown or HTML images and add your image files to your project’s static directory. You can find out more about using this directory in Adding static content.
Images used on this site
Images used as background images in this site are in the public domain and can be used freely. The porridge image in the example site is by iha31 from Pixabay.
2.7 - Print Support
Making it easier to print entire sections of documentation.
Individual documentation pages print well from most browsers as the layouts have been styled to omit navigational chrome from the printed output.
On some sites, it can be useful to enable a “print entire section” feature (as seen in this user guide). Selecting this option renders the entire current top-level section (such as Content and Customization for this page) with all of its child pages and sections in a format suited to printing, complete with a table of contents for the section.
To enable this feature, add the “print” output format in your site’s config.toml file for the “section” type:
[outputs]section=["HTML","RSS","print"]
The site should then show a “Print entire section” link in the right hand navigation.
Further Customization
Disabling the ToC
To disable showing the the table of contents in the printable view, set the disable_toc param to true, either in the page front matter, or in config.toml:
[params.print]disable_toc=true
Layout hooks
A number of layout partials and hooks are defined that can be used to customize the printed format. These can be found in layouts/partials/print.
Hooks can be defined on a per-type basis. For example, you may want to customize the layouts of heading for “blog” pages vs “docs”. This can be achieved by creating layouts/partials/print/page-heading-<type>.html - eg. page-heading-blog.html. It defaults to using the page title and description as a heading.
Similarly, the formatting for each page can be customized by creating layouts/partials/print/content-<type>.html.
2.8 - Analytics, User Feedback, SEO
Add Google Analytics tracking to your site, use the “was this page helpful?” widget data, disable the widget on a single page or all pages, and change the response text. See what data is used to create the meta description tag for SEO.
Adding Analytics
The Docsy theme contains built-in support for Google Analytics via Hugo’s internal template, which is included in the theme. Once you set Analytics up as described below, usage information for your site (such as page views) is sent to your Google Analytics account.
Setup
Ensure you have set up a Google Analytics property for your site: this gives you an Analytics ID to add to your config, which Docsy in turn adds to all your site’s pages.
Open config.toml.
Enable Google Analytics by setting the Tracking ID property to your site’s Analytics ID.
[services.googleAnalytics]
id = "UA-00000000-0"
Save and close config.toml.
Ensure that your site is built with HUGO_ENV="production", as Docsy only adds Analytics tracking to production-ready sites. You can specify this variable as a command line flag to Hugo:
$ env HUGO_ENV="production" hugo
Alternatively, if you’re using Netlify, you can specify it as a Netlify deployment setting in netlify.toml or the Netlify UI, along with the Hugo version.
User Feedback
By default Docsy puts a “was this page helpful?” feedback widget at the bottom of every
documentation page, as shown in Figure 1.
Figure 1. The feedback widget, outlined in red
After clicking Yes the user should see a response like Figure 2. You can configure the
response text in config.toml.
Figure 2. An example Yes response
How is this data useful?
When you have a lot of documentation, and not enough time to update it all, you can use the
“was this page helpful?” feedback data to help you decide which pages to prioritize. In general,
start with the pages with a lot of pageviews and low ratings. “Low ratings” in this context
means the pages where users are clicking No — the page wasn’t helpful — more often than
Yes — the page was helpful. You can also study your highly-rated pages to develop hypotheses
around why your users find them helpful.
In general, you can develop more certainty around what patterns your users find helpful or
unhelpful if you introduce isolated changes in your documentation whenever possible. For example,
suppose that you find a tutorial that no longer matches the product. You update the instructions,
check back in a month, and the score has improved. You now have a correlation between up-to-date
instructions and higher ratings. Or, suppose you study your highly-rated pages and discover that
they all start with code samples. You find 10 other pages with their code samples at the bottom,
move the samples to the top, and discover that each page’s score has improved. Since
this was the only change you introduced on each page, it’s more reasonable to believe that
your users find code samples at the top of pages helpful. The scientific method, applied to
technical writing, in other words!
Setup
Open config.toml.
Ensure that Google Analytics is enabled, as described above.
Set the response text that users see after clicking Yes or No.
[params.ui.feedback]
enable = true
yes = 'Glad to hear it! Please <a href="https://github.com/USERNAME/REPOSITORY/issues/new">tell us how we can improve</a>.'
no = 'Sorry to hear that. Please <a href="https://github.com/USERNAME/REPOSITORY/issues/new">tell us how we can improve</a>.'
Save and close config.toml.
Access the feedback data
This section assumes basic familiarity with Google Analytics. For example, you should know how
to check pageviews over a certain time range and navigate between accounts if you have access to
multiple documentation sites.
Open Google Analytics.
Open Behavior > Events > Overview.
In the Event Category table click the Helpful row. Click view full report if
you don’t see the Helpful row.
Click Event Label. You now have a page-by-page breakdown of ratings.
Here’s what the 4 columns represent:
Total Events is the total number of times that users clicked eitherYes or No.
Unique Events provides a rough indication of how frequently users are rating your pages per
session. For example, suppose your Total Events is 5000, and Unique Events is 2500.
This means that you have 2500 users who are rating 2 pages per session.
Event Value isn’t that useful.
Avg. Value is the aggregated rating for that page. The value is always between 0
and 1. When users click No a value of 0 is sent to Google Analytics. When users click
Yes a value of 1 is sent. You can think of it as a percentage. If a page has an
Avg. Value of 0.67, it means that 67% of users clicked Yes and 33% clicked No.
The underlying Google Analytics infrastructure that stores the “was this page helpful?” data is
called Events. See docsy pull request #1 to see exactly
what happens when a user clicks Yes or No. It’s just a click event listener that
fires the Google Analytics JavaScript function for logging an Event, disables the Yes and
No buttons, and shows the response text.
Disable feedback on a single page
Add hide_feedback: true to the page’s front matter.
Disable feedback on all pages
Set params.ui.feedback.enable to false in config.toml:
Google recommends using the description meta tag to tell search engines what your page is about. The Docsy theme creates and populates this meta tag for you in the layouts/partials/head.html file:
.Page.Description is the text from the descriptionfrontmatter field. If the page’s frontmatter does not have a description, the first 150 characters of the page content is used instead.
For example, if your front matter description is:
---
description: >
Add Google Analytics tracking to your site.
---
Then the meta description tag on the rendered page is:
<metaname="description"content="Add Google Analytics tracking to your site.">
You can add additional meta tags to your own copy of the head-end.html partial. See Customizing templates for more information.
2.9 - Repository Links
Help your users interact with your source repository.
The Docsy docs and blog layouts include links for readers to edit the page or create issues for your docs or project via your site’s source repository. The current generated links for each docs or blog page are:
View page source: Brings the user to the page source in your docs repo.
Edit this page: Brings the user to an editable version of the page content in their fork (if available) of your docs repo. If the user doesn’t have a current fork of your docs repo, they are invited to create one before making their edit. The user can then create a pull request for your docs.
Create child page: Brings the user to a create new file form in their fork of your docs repo. The new file will be located as a child of the page they clicked the link on. The form will be pre-populated with a template the user can edit to create their page. You can change this by adding assets/stubs/new-page-template.md to your own project.
Create documentation issue: Brings the user to a new issue form in your docs repo with the name of the current page as the issue’s title.
Create project issue (optional): Brings the user to a new issue form in your project repo. This can be useful if you have separate project and docs repos and your users want to file issues against the project feature being discussed rather than your docs.
This page shows you how to configure these links.
Currently, Docsy supports only GitHub repository links “out of the box”. If you are using another repository such as Bitbucket and would like generated repository links, feel free to add a feature request or update our theme.
Link configuration
There are four variables you can configure in config.toml to set up links, as well as one in your page metadata.
github_repo
The URL for your site’s source repository. This is used to generate the Edit this page, Create child page, and Create documentation issue links.
github_repo="https://github.com/google/docsy"
github_subdir (optional)
Specify a value here if your content directory is not in your repo’s root directory. For example, this site is in the userguide subdirectory of its repo. Setting this value means that your edit links will go to the right page.
github_subdir="userguide"
github_project_repo (optional)
Specify a value here if you have a separate project repo and you’d like your users to be able to create issues against your project from the relevant docs. The Create project issue link appears only if this is set.
Specify a value here if you have would like to reference a different branch for the other github settings like Edit this page or Create project issue.
github_branch="release"
path_base_for_github_subdir (optional)
Suppose that the source files for all of the pages under content/some-section
come from another repo, such as a git submodule. Add settings like these to
the section’s index page so that the repository links for all pages in that
section refer to the originating repo:
---title:Some super sectioncascade:github_repo:https://github.com/some-username/another-repo/github_subdir:docspath_base_for_github_subdir:content/some-section...---
As an example, consider a page at the path
content/some-section/subpath/some-page.md with github_branch globally set to
main. The index page settings above will generate the following edit link for
some-page.md:
If you only have a single page originating from another repo, then omit the
cascade key and write, at the top-level, the same settings as illustrated
above.
If you’d like users to create project issues in the originating repo as well,
then also set github_project_repo, something like this:
In situations where a page originates from a file under a different name, you
can specify from and to path-rename settings. Here’s an example where an
index file is named README.md in the originating repo:
This can be useful if you have page source files in multiple Git repositories,
or require a non-GitHub URL. Pages using this value have Edit this page
links only.
Disabling links
You can use CSS to selectively disable (hide) links. For example, add the
following to your projects’s _styles_project.scss file
to hide Create child page links from all pages:
.td-page-meta--child{display:none!important;}
Each link kind has an associated unique class named .td-page-meta--KIND, as
defined by the following table:
Link kind
Class name
View page source
.td-page-meta--view
Edit this page
.td-page-meta--edit
Create child page
.td-page-meta--child
Create documentation issue
.td-page-meta--issue
Create project issue
.td-page-meta--project-issue
Of course, you can also use these classes to give repository links unique styles
for your project.
2.10 - Taxonomy Support
Structure the content using taxonomies like tags, categories, labels.
Docsy supports Hugo’s Taxonomies (see: https://gohugo.io/content-management/taxonomies/) in its docs and blog section. You can see the default layout and can test the behavior of the generated links on this page.
Terminology
To understand the usage of taxonomies you should understand the following terminology:
Taxonomy
a categorization that can be used to classify content - e.g.: Tags, Categories, Projects, People
Term
a key within the taxonomy - e.g. within projects: Project A, Project B
Value
a piece of content assigned to a term - e.g. a page of your site, that belongs to a specific project
If you want to enable taxonomies in Docsy you have to delete (or comment out) this line in your projects config.toml. Then the taxonomy pages for tags and categories will be generated by Hugo. If you want to use other taxonomies you have to define them in your config.toml. If you want to use beside your own taxonomies also the default taxonomies tags and categories, you also have to define them beside your own taxonomies. You need to provide both the plural and singular labels for each taxonomy.
With the following example you define a additional taxonomy projects beside the default taxonomies tags and categories:
You can use the following parameters in your projects config.toml to control the output of the assigned taxonomy terms for each article resp. page of your docs and/or blog section in Docsy or a “tag cloud” in Docsy’s right sidebar:
[params.taxonomy]taxonomyCloud=["projects","tags"]# set taxonomyCloud = [] to hide taxonomy cloudstaxonomyCloudTitle=["Our Projects","Tag Cloud"]# if used, must have same lang as taxonomyCloudtaxonomyPageHeader=["tags","categories"]# set taxonomyPageHeader = [] to hide taxonomies on the page headers
The settings above would only show a taxonomy cloud for projects and tags (with the headlines “Our Projects” and “Tag Cloud”) in Docsy’s right sidebar and the assigned terms for the taxonomies tags and categories for each page.
To disable any taxonomy cloud you have to set the Parameter taxonomyCloud = [] resp. if you doesn’t want to show the assigned terms you have to set taxonomyPageHeader = [].
As default the plural label of a taxonomy is used as it cloud title. You can overwrite the default cloud title with taxonomyCloudTitle. But if you do so, you have to define a manual title for each enabled taxonomy cloud (taxonomyCloud and taxonomyCloudTitle must have the same length!).
If you doesn’t set the parameters taxonomyCloud resp. taxonomyPageHeader the taxonomy clouds resp. assigned terms for all defined taxonomies will be generated.
Partials
The by default used partials for displaying taxonomies are so defined, that you should be able to use them also easily in your own layouts.
taxonomy_terms_article
The partial taxonomy_terms_article shows all assigned terms of an given taxonomy (partial parameter taxo) of an article respectively page (partial parameter context, most of the time the current page or context .).
Example usage in layouts/docs/list.html for the header of each page in the docs section:
The partial taxonomy_terms_article_wrapper is a wrapper for the partial taxonomy_terms_article with the only parameter context (most of the time the current page or context .) and checks the taxonomy parameters of you projects config.toml to loop threw all listed taxonomies in the parameter taxonomyPageHeader resp. all defined taxonomies of your page, if taxonomyPageHeader isn’t set.
taxonomy_terms_cloud
The partial taxonomy_terms_cloud shows all used terms of an given taxonomy (partial parameter taxo) for your site (partial parameter context, most of the time the current page or context .) and with the parameter title as headline.
Example usage in partial taxonomy_terms_clouds for showing all defined taxonomies and its terms:
As an example this will gave you for following HTML markup for the taxonomy categories:
<divclass="taxonomy taxonomy-terms-cloud taxo-categories"><h5class="taxonomy-title">Cloud of Categories</h5><ulclass="taxonomy-terms"><li><aclass="taxonomy-term"href="//localhost:1313/categories/category-1/"data-taxonomy-term="category-1"><spanclass="taxonomy-label">category 1</span><spanclass="taxonomy-count">3</span></a></li><li><aclass="taxonomy-term"href="//localhost:1313/categories/category-2/"data-taxonomy-term="category-2"><spanclass="taxonomy-label">category 2</span><spanclass="taxonomy-count">1</span></a></li><li><aclass="taxonomy-term"href="//localhost:1313/categories/category-3/"data-taxonomy-term="category-3"><spanclass="taxonomy-label">category 3</span><spanclass="taxonomy-count">2</span></a></li><li><aclass="taxonomy-term"href="//localhost:1313/categories/category-4/"data-taxonomy-term="category-4"><spanclass="taxonomy-label">category 4</span><spanclass="taxonomy-count">6</span></a></li></ul></div>
taxonomy_terms_clouds
The partial taxonomy_terms_clouds is a wrapper for the partial taxonomy_terms_cloud with the only parameter context (most of the time the current page or context .) and checks the taxonomy parameters of you projects config.toml to loop threw all listed taxonomies in the parameter taxonomyCloud resp. all defined taxonomies of your page, if taxonomyCloud isn’t set.
Multi language support for taxonomies
The taxonomy terms associated content gets only counted and linked WITHIN the language! The control parameters for the taxonomy support can also get assigned language specific.
2.11 - Diagrams and Formulae
Add generated diagrams and scientific formulae to your site.
Docsy has built-in support for a number of diagram creation and typesetting tools you can use to add rich content to your site, including \(\KaTeX\), Mermaid, Diagrams.net, PlantUML, and MarkMap.
\(\LaTeX\) support with \(\KaTeX\)
\(\LaTeX\) is a high-quality typesetting system for the production of technical and scientific documentation. Due to its excellent math typesetting capabilities, \(\TeX\) became the de facto standard for the communication and publication of scientific documents, especially if these documents contain a lot of mathematical formulae. Designed and mostly written by Donald Knuth, the initial version was released in 1978. Dating back that far, \(\LaTeX\) has pdf as its primary output target and is not particularly well suited for producing HTML output for the Web. Fortunately, with \(\KaTeX\) there exists a fast and easy-to-use JavaScript library for \(\TeX\) math rendering on the web, which was integrated into the Docsy theme.
With \(\KaTeX\) support enabled in Docsy, you can include complex mathematical formulae into your web page, either inline or centred on its own line. Since \(\KaTeX\) relies on server side rendering, it produces the same output regardless of your browser or your environment. Formulae can be shown either inline or in display mode:
Inline formulae
The following code sample produces a text line with three inline formulae:
When \\(a \ne 0\\), there are two solutions to \\(ax^2 + bx + c= 0\\) and they are \\(x = {-b \pm\sqrt{b^2-4ac}\over 2a}.\\)
When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c= 0\) and they are \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\)
Formulae in display mode
The following code sample produces an introductory text line followed by a formula numbered as (1) residing on her own line:
The probability of getting \\(k\\) heads when flipping \\(n\\) coins is:
$$\tag*{(1)} P(E)= {n \choose k} p^k (1-p)^{n-k}$$
The probability of getting \(k\) heads when flipping \(n\) coins is:
$$\tag*{(1)} P(E) = {n \choose k} p^k (1-p)^{n-k}$$
Tip
This wiki page provides in-depth information about typesetting mathematical formulae using the \(\LaTeX\) typesetting system.
Enabling and configuring \(\LaTeX\) support
To enable/disable \(\KaTeX\) support inside the Docsy theme, update config.toml:
[params.katex]enable=true
Additionally, you can customize various \(\KaTeX\) options inside config.toml, if needed:
[params.katex]# enable/disable KaTeX supportenable=true# Element(s) scanned by auto render extension. Default: document.bodyhtml_dom_element="document.body"[params.katex.options]# If true (the default), KaTeX will throw a ParseError when it encounters an# unsupported command or invalid LaTeX. If false, KaTeX will render unsupported# commands as text, and render invalid LaTeX as its source code with hover text# giving the error, in the color given by errorColor.throwOnError=falseerrorColor="#CD5C5C"# This is a list of delimiters to look for math, processed in the same order as# the list. Each delimiter has three properties:# left: A string which starts the math expression (i.e. the left delimiter).# right: A string which ends the math expression (i.e. the right delimiter).# display: Whether math in the expression should be rendered in display mode.[[params.katex.options.delimiters]]left="$$"right="$$"display=true[[params.katex.options.delimiters]]left="$"right="$"display=false[[params.katex.options.delimiters]]left="\\("right="\\)"display=false[[params.katex.options.delimiters]]left="\\["right='\\]'display=true
For a complete list of options and their detailed description, have a look at the documentation of \({\KaTeX}’s\) Rendering API options and of \({\KaTeX}’s\) configuration options.
Display of Chemical Equations and Physical Units
mhchem is a \(\LaTeX\) package for typesetting chemical molecular formulae and equations. Fortunately, \(\KaTeX\) provides the mhchemextension that makes the mhchem package accessible when authoring content for the web. Since this extension was integrated into the Docsy theme, you can write beautiful chemical equations easily once mhchem support is enabled inside your config.toml:
With mhchem extension enabled, you can easily include chemical equations into your page. The equations can be shown either inline or can reside on its own line. The following code sample produces a text line including a chemical equation:
*Precipitation of barium sulfate:* \\(\ce{SO4^2- + Ba^2+ -> BaSO4 v}\\)
Precipitation of barium sulfate: \(\ce{SO4^2- + Ba^2+ -> BaSO4 v}\)
More complex equations, like the one shown in the code sample below, should be displayed on their own line:
The manual for mchem’s input syntax provides in-depth information about typesetting chemical formulae and physical units using the mhchem tool.
Use of mhchem is not limited to the authoring of chemical equations, using the included \pu command, pretty looking physical units can be written with ease, too. The following code sample produces two text lines with four numbers plus their corresponding physical units:
* Scientific number notation: \\(\pu{1.2e3 kJ}\\) or \\(\pu{1.2E3 kJ}\\) \\
* Divisions: \\(\pu{123 kJ/mol}\\) or \\(\pu{123 kJ//mol}\\)
Scientific number notation: \(\pu{1.2e3 kJ}\) or \(\pu{1.2E3 kJ}\)
Divisions: \(\pu{123 kJ/mol}\) or \(\pu{123 kJ//mol}\)
For a complete list of options when authoring physical units, have a look at the section on physical units in the mhchem documentation.
Diagrams with Mermaid
Mermaid is a Javascript library for rendering simple text definitions to useful diagrams in the browser. It can generate a variety of different diagram types, including flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, user journey diagrams, Gantt charts and pie charts.
With Mermaid support enabled in Docsy, you can include the text definition of a Mermaid diagram inside a code block, and it will automatically be rendered by the browser as soon as the page loads.
The great advantage of this is anyone who can edit the page can now edit the diagram - no more hunting for the original tools and version to make a new edit.
For example, the following defines a simple flowchart:
```mermaid
graph LR
Start --> Need{"Do I need diagrams"}
Need -- No --> Off["Set params.mermaid.enable = false"]
Need -- Yes --> HaveFun["Great! Enjoy!"]
```
Automatically renders to:
graph LR
Start --> Need{"Do I need diagrams"}
Need -- No --> Off["Set params.mermaid.enable = false"]
Need -- Yes --> HaveFun["Great! Enjoy!"]
To enable/disable Mermaid, update config.toml:
[params.mermaid]enable=true
You also need to disable the guessSyntax from markup highlighting in config.toml for Mermaid to work:
[markup][markup.highlight]guessSyntax="false"
You can also update settings for Mermaid, such as themes, padding, etc:
Settings can also be overridden on a per-diagram basis by making use of the %%init%% header at the start of the diagram definition. See the Mermaid theming documentation.
UML Diagrams with PlantUML
PlantUML is an alternative to Mermaid that lets you quickly create UML diagrams, including sequence diagrams, use case diagrams, and state diagrams. Unlike Mermaid diagrams, which are entirely rendered in the browser, PlantUML uses a PlantUML server to create diagrams. You can use the provided default demo server (not recommended for production use), or run a server yourself. PlantUML offers a wider range of image types than Mermaid, so may be a better choice for some use cases.
```plantuml
participant participant as Foo
actor actor as Foo1
boundary boundary as Foo2
control control as Foo3
entity entity as Foo4
database database as Foo5
collections collections as Foo6
queue queue as Foo7
Foo -> Foo1 : To actor
Foo -> Foo2 : To boundary
Foo -> Foo3 : To control
Foo -> Foo4 : To entity
Foo -> Foo5 : To database
Foo -> Foo6 : To collections
Foo -> Foo7: To queue
```
Automatically renders to:
participant participant as Foo
actor actor as Foo1
boundary boundary as Foo2
control control as Foo3
entity entity as Foo4
database database as Foo5
collections collections as Foo6
queue queue as Foo7
Foo -> Foo1 : To actor
Foo -> Foo2 : To boundary
Foo -> Foo3 : To control
Foo -> Foo4 : To entity
Foo -> Foo5 : To database
Foo -> Foo6 : To collections
Foo -> Foo7: To queue
To enable/disable PlantUML, update config.toml:
[params.plantuml]
enable = true
Other optional settings are:
[params.plantuml]
enable = true
theme = "default"
#Set url to plantuml server
#default is http://www.plantuml.com/plantuml/svg/
svg_image_url = "https://www.plantuml.com/plantuml/svg/"
#By default the plantuml implementation uses <img /> tags to display UML diagrams.
#When svg is set to true, diagrams are displayed using <svg /> tags, maintaining functionality like links e.d.
#default = false
svg = true
MindMap support with MarkMap
MarkMap is a Javascript library for rendering simple text definitions to MindMap in the browser.
For example, the following defines a simple MindMap:
Diagrams.net (aka draw.io) provides a free and open source diagram editor that can generate a wider range of diagrams than Mermaid or PlantUML using a web or desktop editor.
SVG and PNG files exported with the tool contain the source code of the original diagram by default, which allows the diagrams.net site to import those images again for edit in the future. Docsy can detect this and automatically add an “edit” button over any image that can be edited using the online site.
Hover over the image below and click edit to instantly start working with it. Clicking the “Save” button will cause the edited diagram to be exported using the same filename and filetype, and downloaded to your browser.
Note
If you’re creating a new diagram, be sure to File -> Export in either svg or png format (svg is usually the best choice) and ensure the “Include a copy of my diagram” is selected so it can be edited again later.
As the diagram data is transported via the browser, the diagrams.net server does not need to access the content on your Docsy server directly at all.
Mouse over the above image and click the edit button!
To disable detection of diagrams, update config.toml:
[params.drawio]enable=false
You can also deploy and use your own server for editing diagrams, in which case update the configuration to point to that server:
If you’d like to provide site content in multiple languages, the Docsy theme and Hugo make it easy to both add your translated content and for your users to navigate between language versions.
Content and configuration
To add content in multiple languages, you first need to define the available languages in a languages section in your site configuration. Each language can have its own language-specific configuration. For example, the Docsy Example Site config specifies that it provides content in English and Norwegian, and that the language version visitors will see by default is English:
contentDir="content/en"defaultContentLanguage="en"defaultContentLanguageInSubdir=false...[languages][languages.en]title="Docsy"description="Docsy does docs"languageName="English"# Weight used for sorting.weight=1[languages.no]title="Docsy"description="Docsy er operativsystem for skyen"languageName="Norsk"contentDir="content/no"time_format_default="02.01.2006"time_format_blog="02.01.2006"
Any setting not defined in a [languages] block will fall back to the global value for that setting: so, for example, the content directory used for the site above will be content/en unless the user selects the Norwegian language option.
Once you’ve updated your site config, you create a content root directory for each language version in your source repo, such as content/en for English text, and add your content as usual. See the Hugo Docs on multi-language support for more information.
Attention (only when using docsy as hugo module)
If you have a multi language installation, please make sure that the section [languages] inside your config.toml is declared before the section [module] with the module imports. Otherwise you will run into trouble!
Tip
If there’s any possibility your site might be translated into other languages, consider creating your site with your content in a language-specific subdirectory, as it means you don’t need to move it if you add another language.
For adding multiple language versions of other site elements such as button text, see the internationalization bundles section below.
Selecting a language
If you configure more than one language in config.toml, the Docsy theme adds a language selector drop down to the top-level menu. Selecting a language takes the user to the translated version of the current page, or the home page for the given language.
Internationalization bundles
All UI strings (text for buttons etc.) are bundled inside /i18n in the theme, with a .toml file for each language.
If your chosen language isn’t currently in the theme and you create your own .toml file for all the common UI strings (for example, if you translate the UI text into Japanese and create a copy of en.toml called jp.toml), we recommend you do this in the theme rather than in your own project, so it can be reused by others. Any additional strings or overridden values can be added to your project’s /i18n folder.
Hugo Tip
Run hugo server --i18n-warnings when doing translation work, as it will give you warnings on what strings are missing.
4 - Previews and Deployment
Deploying your Docsy site.
There are multiple possible options for deploying a Hugo site, including Netlify, Firebase Hosting, Bitbucket with Aerobatic, and more; you can read about them all in Hosting and Deployment. Hugo also makes it easy to deploy your site locally for quick previews of your content.
Serving your site locally
Depending on your deployment choice you may want to serve your site locally during development to preview content changes. To serve your site locally:
Ensure you have an up to date local copy of your site files cloned from your repo. Don’t forget to use --recurse-submodules or you won’t pull down some of the code you need to generate a working site.
If you’ve just added the theme as a submodule in a local version of your site and haven’t committed it to a repo yet, you must get local copies of the theme’s own submodules before serving your site.
git submodule update --init --recursive
Ensure you have the tools described in Prerequisites and installation installed on your local machine, including postcss-cli (you’ll need it to generate the site resources the first time you run the server).
Run the hugo server command in your site root. By default your site will be available at http://localhost:1313/.
Now that you’re serving your site locally, Hugo will watch for changes to the content and automatically refresh your site. If you have more than one local git branch, when you switch between git branches the local website reflects the files in the current branch.
Build environments and indexing
By default, Hugo sites built with hugo (rather than served locally with hugo server) have the Hugo build environment production. Deployed Docsy sites with production builds can be indexed by search engines, including Google Custom Search Engines. Production builds also have optimized JavaScript and CSS for live deployment (for example, minified JS rather than the more legible original source).
If you do not want your deployed site to be indexed by search engines (for example if you are still developing your live site), or if you want to build a development version of your site for offline analysis, you can set your Hugo build environment to something else such as development (the default for local deploys with hugo server), test, or another environment name of your choice.
The simplest way to set this is by using the -e flag when specifying or running your hugo command, as in the following example:
hugo -e development
Deployment with Netlify
We recommend using Netlify as a particularly simple way to serve your site from your Git provider (GitHub, GitLab, or BitBucket), with continuous deployment, previews of the generated site when you or your users create pull requests against the doc repo, and more. Netlify is free to use for Open Source projects, with premium tiers if you require greater support.
Before deploying with Netlify, make sure that you’ve pushed your site source to your chosen GitHub (or other provider) repo, following any setup instructions in Using the theme.
Then follow the instructions in Host on Netlify to set up a Netlify account (if you don’t have one already) and authorize access to your GitHub or other Git provider account. Once you’re logged in:
Click New site from Git.
Click your chosen Git provider, then choose your site repo from your list of repos.
In the Deploy settings page:
For your Build command, specify cd themes/docsy && git submodule update -f --init && cd ../.. && hugo. You need to specify this rather than just hugo so that Netlify can use the theme’s submodules. If you don’t want your site to be indexed by search engines, you can add an environment flag to specify a non-production environment, as described in Build environments and indexing.
Click Show advanced.
In the Advanced build settings section, click New variable.
Specify HUGO_VERSION as the Key for the new variable, and 0.73 or later as its Value.
Click Deploy site.
Note
Netlify uses your site repo’s package.json file to install any JavaScript dependencies (like postcss) before building your site. If you haven’t just copied our example site’s version of this file, make sure that you’ve specified all our prerequisites.
For example, if you want to use a version of postcss-cli later than version 8.0.0, you need to ensure that your package.json also specifies postcss separately:
Alternatively, you can follow the same instructions but specify your Deploy settings in a netlify.toml file in your repo rather than in the Deploy settings page. You can see an example of this in the Docsy theme repo (though note that the build command here is a little unusual because the Docsy user guide is inside the theme repo).
If you have an existing deployment you can view and update the relevant information by selecting the site from your list of sites in Netlify, then clicking Site settings - Build and deploy. Ensure that Ubuntu Xenial 16.04 is selected in the Build image selection section - if you’re creating a new deployment this is used by default. You need to use this image to run the extended version of Hugo.
Deployment with Amazon S3 + Amazon CloudFront
There are several options for publishing your web site using Amazon Web Services, as described in this blog post. This section describes the most basic option, deploying your site using an S3 bucket and activating the CloudFront CDN (content delivery network) to speed up the delivery of your deployed contents.
After your registration at AWS, create your S3 bucket, connect it with your domain, and add it to the CloudFront CDN. This blog post has all the details and provides easy to follow step-by-step instructions for the whole procedure.
Download and install the latest version 2 of the AWS Command Line Interface (CLI). Then configure your CLI instance by issuing the command aws configure (make sure you have your AWS Access Key ID and your AWS Secret Access Key at hand):
$ aws configure
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: eu-central-1
Default output format [None]:
Check the proper configuration of your AWS CLI by issuing the command aws s3 ls, this should output a list of your S3 bucket(s).
Inside your config.toml, add a [deployment] section like this one:
Run the command hugo --gc --minify to render the site’s assets into the public/ directory of your Hugo build environment.
Use Hugo’s built-in deploy command to deploy the site to S3:
hugo deploy
Deploying to target "aws" (www.your-domain.tld)
Identified 77 file(s) to upload, totaling 5.3 MB, and 0 file(s) to delete.
Success!
Invalidating CloudFront CDN...
Success!
As you can see, issuing the hugo deploy command automatically invalidates your CloudFront CDN cache.
That’s all you need to do! From now on, you can easily deploy to your S3 bucket using Hugo’s built-in deploycommand!
For more information about the Hugo deploy command, including command line options, see this synopsis. In particular, you may find the --maxDeletes int option or the --force option (which forces upload of all files) useful.
Automated deployment with GitHub actions
If the source of your site lives in a GitHub repository, you can use GitHub Actions to deploy the site to your S3 bucket as soon as you commit changes to your GitHub repo. Setup of this workflow is described in this blog post.
Handling aliases
If you are using aliases for URL management, you should have a look at this blog post. It explains how to turn aliases into proper 301 redirects when using Amazon S3.
If S3 does not meet your needs, consider AWS Amplify Console. This is a more advanced continuous deployment (CD) platform with built-in support for the Hugo static site generator. A starter can be found in Hugo’s official docs.
5 - Examples
Some examples of Docsy in action!
One of the best ways to see what Docsy can do, and learn how to configure a site with it, is to see some real projects. In addition to our provided Docsy Example Project, there are several live sites already using the theme. Please add your own examples once you’ve got a production site up and running with Docsy!
We hope to continue to make improvements to the theme along with the Docsy community.
If you have cloned the example site (or are otherwise using the theme as a Hugo Module or Git submodule), you can easily update the Docsy theme in your site yourself. If you have cloned the theme itself into your own project you can also update, though you may need to resolve merge conflicts.
Updating Docsy means that your site will build using the latest version of Docsy at HEAD and include
all the new commits or changes that have been merged since the point in time that you initially added the Docsy
submodule, or last updated. Updating won’t affect any modifications that you made in your own project to
override the Docsy look and feel, as your overrides
don’t modify the theme itself. For details about what has changed in the theme since your last update, see the list of
Docsy commits.
If you have been using the theme as a Git submodule, you can also update your site to use Docsy as a Hugo Module. This is the latest and simplest way to pull in a Hugo theme from its repository. If you’re not ready to migrate to Hugo Modules yet, don’t worry, your site will still work and you can continue to update your submodule as before.
6.1 - Update the Docsy Hugo Module
Update the Docsy theme to the latest version using Hugo Modules.
When using the Docsy theme as a Hugo Module, updating your theme is really easy.
At the command prompt, change to the root directory of your existing site.
cd /path/to/my-existing-site
Then invoke hugo’s module get subcommand with the update flag:
hugo mod get -u github.com/google/docsy
Hugo automatically pulls in the latest theme version. That’s it, your update is done!
Tip
If you want to set your module to a certain version inside the docsy theme repo, simply specific the name of the tag representing this version (here: 0.2.0) when updating your theme:
hugo mod get -u github.com/google/docsy@0.2.0
Instead of a version tag, you can also specify a commit hash inside the repo (here: c7b9901e) when updating your theme:
hugo mod get -u github.com/google/docsy@c7b9901e
6.2 - Update Docsy without Hugo Modules
Update the Docsy theme to the latest version using submodules or git pull.
If you aren’t using Hugo Modules, depending on how you chose to install Docsy on your existing site, use one of the following two procedures to update your theme.
cd /path/to/my-existing-site
hugo mod init github.com/me-at-github/my-existing-site
hugo mod get github.com/google/docsy@0.2.0-pre
hugo mod get github.com/google/docsy/dependencies@0.2.0-pre
sed -i '/theme = \["docsy"\]/d' config.toml
cat >> config.toml <<EOL
[module]
[[module.imports]]
path = "github.com/google/docsy"
[[module.imports]]
path = "github.com/google/docsy"
EOL
hugo server
cd my-existing-site
hugo mod init github.com/me-at-github/my-existing-site
hugo mod get github.com/google/docsy@0.2.0-pre
hugo mod get github.com/google/docsy/dependencies@0.2.0-pre
findstr /v /c:"theme = [\"docsy\"]" config.toml > config.toml.temp
move /Y config.toml.temp config.toml
(echo [module]^
[[module.imports]]^
path = "github.com/google/docsy"^
[[module.imports]]^
path = "github.com/google/docsy")>>config.toml
hugo server
Detailed conversion instructions
Import the Docsy theme module as a dependency of your site
At the command prompt, change to the root directory of your existing site.
cd /path/to/my-existing-site
Only sites that are Hugo Modules themselves can import other Hugo Modules. Turn your existing site into a Hugo Module by running the following command from your site directory, replacing github.com/me/my-existing-site with your site repository:
hugo mod init github.com/me/my-existing-site
This creates two new files, go.mod for the module definitions and go.sum which holds the checksums for module verification.
Next declare the Docsy theme module as a dependency for your site. You must also declare the submodule dependencies as a second dependency. This submodule pulls in both a workaround for a bug in Go’s module management and the dependencies bootstrap and Font-Awesome.
hugo mod get github.com/google/docsy@0.2.0-pre
hugo mod get github.com/google/docsy/dependencies@0.2.0-pre
These commands add both the docsy theme module and the dependencies submodule to your definition file go.mod.
Update your config file
In your config.toml file, update the theme setting to use Hugo Modules. Find the following line:
If you have a multi language installation, please make sure that the section [languages] inside your config.toml is declared before the section [module] with the module imports. Otherwise you will run into trouble!
Check validity of your configuration settings
To make sure that your configuration settings are correct, run the command hugo mod graph which prints a module dependency graph:
hugo mod graph
hugo: collected modules in 1092 ms
github.com/me/my-existing-site github.com/google/docsy@0.2.0-pre
github.com/me/my-existing-site github.com/google/docsy/dependencies@0.2.0-pre
github.com/google/docsy/dependencies@0.2.0-pre github.com/twbs/bootstrap@v4.6.1+incompatible
github.com/google/docsy/dependencies@0.2.0-pre github.com/FortAwesome/Font-Awesome@v0.0.0-20210804190922-7d3d774145ac
Make sure that three lines with dependencies docsy, bootstrap and Font-Awesome are listed. If not, please double check your config settings.
Tip
In order to clean up your module cache, issue the command hugo mod clean
hugo mod clean
hugo: collected modules in 995 ms
hugo: cleaned module cache for "github.com/FortAwesome/Font-Awesome"
hugo: cleaned module cache for "github.com/google/docsy"
hugo: cleaned module cache for "github.com/google/docsy/dependencies"
hugo: cleaned module cache for "github.com/twbs/bootstrap"
Clean up your repository
Since your site now uses Hugo Modules, your previously used themes directory can be removed:
rm -rf /path/to/your/theme
If your Docsy theme was installed as submodule, you can remove the theme submodule:
With your submodule deleted, now delete the relevant line from the hidden submodule definition file .gitmodules, too. If this is the only line, you can delete the file altogether.
rm .gitmodules
Finally, delete the now untracked submodule files and also clean up the internal directory that git used to store your git submodules:
Be careful when using the rm -rf command, make sure that you don’t inadvertently delete any productive data files!
7 - Best Practices
Optional guidance and recommendations about organizing, authoring, and managing your technical documentation.
Use this section to learn about some of the best practices around creating technical documentation with Docsy.
7.1 - Hugo Content Tips
Tips for authoring content for your Docsy-themed Hugo site.
Docsy is a theme for the Hugo static site generator.
If you’re not already familiar with Hugo and, in particular, its version of Markdown, this page provides some
useful tips and potential gotchas for adding and editing content for your site. Feel free to add your own!
Linking
By default, regular relative URLs in links are left unchanged by Hugo (they’re still relative links in your site’s generated HTML), hence some hardcoded relative links like [relative cross-link](../../peer-folder/sub-file.md) might behave unexpectedly compared to how they work on your local file system. You may find it helpful to use some of Hugo’s built-in link shortcodes to avoid broken links in your generated site. For example a {{< ref "filename.md" >}} link in Hugo will actually
find and automatically link to your file named filename.md.
Note, however, that ref and relref links don’t work with _index or index files (for example, this site’s content landing page): you’ll need to use regular Markdown links to section landing or other index pages. Specify these links relative to the site’s root URL, for example: /docs/adding-content/.
As of version 0.60.0, Hugo uses the Goldmark Markdown processor.
Prior to that version, Blackfriday was Hugo’s default Markdown processor.
This processor can be sensitive when it come to content that’s deeply nested in a list. In particular, be aware that
this known issue can surface if or when you have multiple authors and
other contributors who might mix tabs and spaces when indenting lists, or fail to indent properly.
An additional factor here is that because GitHub uses a different Markdown processor, GitHub markdown and the editor UI may
render some nested lists properly, while Blackfriday might render that same content poorly. For example, the count in a
numbered list might restart, or your nested content within a list is not indented
(shows as a peer element instead of a nested child element). You may want to recommend in your contribution guidelines
(as we do) that contributors preview their content with Hugo
(or use Netlify’s preview feature for PRs if that’s your chosen deployment tool) to ensure their content renders correctly
with Blackfriday.
Tip
Per comments on the known issue,
users still using Blackfriday as markup processor will achieve consistent behavior when using tabs for indentation. If you don’t like tabs and want to use spaces for indentation, make sure you use 4 spaces for one indentation level, other you might run into trouble. Therefore, when using spaces for indentation,
consider configuring your local editor to use 4 spaces when the Tab key is pressed.
7.2 - Organizing Your Content
Optional guidance and recommendations on how to organize your documentation site.
If you have a look at our Example Site, you’ll see that we’ve organized
the Documentation section into a number of subsections, each with some recommendations about what you might put
in that section.
Do I need to use this structure?
Absolutely not! The site structure in the Example Site was created to meet the needs of large docsets for large
products with lots of features, potential tasks, and reference elements. For a simpler docset (like this one!),
it’s fine to just structure your docs around specific features that your users need to know about. Even for larger
documentation sets, you may find that the structure isn’t useful “as is”, or that you don’t need to use all the
section types.
We do recommend that (as we’ve done here) you provide at least:
An Overview of the product (either on the docs landing page or a separate Overview page) that tells the user
why they should be interested in your project.
A Getting Started page.
Some Examples.
You may also want to create some tasks/how-tos for your project’s features. Feel free to copy this Docsy user guide
site or even just the docs section instead if you like this simpler structure better.
Tip
If you want to copy this guide, be aware that its source files are inside the Docsy theme repo, and so it doesn’t have its own themes/ directory: instead, we run hugo server --themesDir ../.. to use Docsy from its parent directory. You may want to either copy the site and add a themes/ directory with Docsy, or just copy the docs/ folder into your existing site’s content root.
We based the Example Site structure on our own experiences creating (and using) large documentation sets for
different types of project and on user research carried out on some of our bigger sites. In user studies we saw that
users cared most about and immediately looked for a Get Started or Getting Started section
(so they could, well, get started), and some examples to explore and copy, so we made those into prominent top-level doc
sections in our site. Users also wanted to find “recipes” that they could easily look up to perform specific tasks and
put together to create their own applications or projects, so we suggest that you add this kind of content as Tasks.
Other content types such as conceptual docs, reference docs, and end-to-end tutorials are less important for all doc sets,
particularly for smaller projects. We emphasize in our Example Site that these sections are optional.
We hope to improve the Example Site structure further as we learn more about how users interact with technical
documentation, particularly for Open Source projects.
Writing style guide
This guide and the example site just address how to organize your documentation content into pages and sections. For some guidance on how to organize and write the content in each page, we recommend the
Google Developer Documentation Style Guide, particularly the
Style Guide Highlights.
8 - Contribution Guidelines
How to contribute to Docsy
Docsy is an open source project and we love getting patches and contributions to make Docsy and its docs even better.
Contributions to this project must be accompanied by a Contributor License
Agreement. You (or your employer) retain the copyright to your contribution;
this simply gives us permission to use and redistribute your contributions as
part of the project. Head over to https://cla.developers.google.com/ to see
your current agreements on file or to sign a new one.
You generally only need to submit a CLA once, so if you’ve already submitted one
(even if it was for a different project), you probably don’t need to do it
again.
Code reviews
All submissions, including submissions by project members, require review. We
use GitHub pull requests for this purpose. Consult
GitHub Help for more
information on using pull requests.
Previewing your changes
As Docsy is a theme rather than a site, you can’t serve the theme directly to check your changes work. Instead use your updated local theme in a local copy of the Docsy example site (copy or make your changes in the themes/docsy directory) and preview from there. Alternatively, clone the Docsy theme repo and test your changes in a local copy of this site, as described below.
Alternatively, if there’s something you’d like to see in Docsy (or if you’ve found something that isn’t working the way you’d expect), but you’re not sure how to fix it yourself, please create an issue.
Contributing to these docs
This user guide is, like our example site, a Docsy site that uses the Hugo static site generator. We welcome updates to the docs!
We use Netlify to manage the deployment of the site and provide previews of doc updates. The instructions here assume you’re familiar with basic GitHub workflows.
Quick start with Netlify
Fork the Docsy repo on GitHub: this site’s files live in the userguide subdirectory.
Make your changes and send a pull request (PR).
If you’re not yet ready for a review, add “WIP” to the PR name to indicate
it’s a work in progress. (Don’t add the Hugo property
“draft = true” to the page front matter, because that prevents the
auto-deployment of the content preview described in the next point.)
Wait for the automated PR workflow to do some checks. When it’s ready,
you should see a comment like this: deploy/netlify — Deploy preview ready!
Click Details to the right of “Deploy preview ready” to see a preview
of your updates.
Continue updating your doc and pushing your changes until you’re happy with
the content.
When you’re ready for a review, add a comment to the PR, and remove any
“WIP” markers.
Updating a single page
If you’ve just spotted something you’d like to change while using the docs, Docsy has a shortcut for you:
Click Edit this page in the top right hand corner of the page.
If you don’t already have an up to date fork of the project repo, you are prompted to get one - click Fork this repository and propose changes or Update your Fork to get an up to date version of the project to edit. The appropriate page in your fork is displayed in edit mode.
If you want to run your own local Hugo server to preview your changes as you work:
Follow the instructions in Getting started to install Hugo and any other tools you need.
Fork the Docsy repo into your own project, then create a local copy using git clone. Don’t forget to use --recurse-submodules or you won’t pull down some of the code you need to generate a working site.
Change to the userguide directory and run the following Hugo command to build the site and start the Hugo server.
Note that you need the themesDir flag because the site files are inside the theme repo.
cd userguide
hugo server --themesDir ../..
By default your site will be available at http://localhost:1313/. Now that you’re serving your site locally, Hugo will watch for changes to the content and automatically refresh your site.
Continue with the usual GitHub workflow to edit files, commit them, push the
changes up to your fork, and create a pull request.
Creating an issue
If there’s something you’d like to see in the docs, but you’re not sure how to fix it yourself, please create an issue in this repository. You can also create an issue about a specific page by clicking the Create Issue button in the top right hand corner of the page.
