Documentation Guidelines

For a full explanation of how to work in our Documentation files, you need to get acquainted with Hugo (our rendering engine), Learn (our Hugo Theme), and Asciidoc (the markup style we use).

The explanations below are simply a shortlist of some frequently used syntax, and a few recommendations regarding naming conventions and other rules we adhere to, for consistency and other practical reasons.

Placing files

Most often the files you will want to edit will be under content directory. That’s where you find the main sections of the guide, User, Developer, Admin, Community and Technical Blog.

You may create new directories inside these, as appropriate for sub-sections; and you can create new files. You should understand the way Hugo uses the directories and file placements to generate content. We are currently not using Hugo’s Page Bundles, though we plan to use them in the future.

Naming Files

Both for directory names and file names, we use the page titles as they appear in the front-matter, but use only lowercase, and no spaces or special characters.

Basically, we are trying to emulate the way Hugo produces the final content under the public directory so that there isn’t much difference between the source and the rendered content. We’ve found this tends to facilitate managing the content.

So a page in directory Installation Guide titled Downloading & Installing can get a filename of installation-guide/downloading-installing.adoc.

Naming Translated Files

For translations, we keep the English file name (that’s how Hugo gets the fact that these are translated versions of the same thing) but add a language code before the .adoc extension.

So these are all translations of the same file (English, Spanish, Russian):


Note that we could have used requirements.en.adoc for the English version, but we don’t do that. We keep the default language (English) without any language code at all.

Front-matter and Special Codes

Each Asciidoc content file will start with a section called Front-matter:

title: Documentation Guidelines
weight: 50

Although there are many things that can be defined here, we require only the title and weight properties.

The weight defines the position in the table of contents, that is, the order within the section where the page belongs. We use increments of 10 for weight so that if we want to insert a new page in between two other pre-existing pages, it’s easier to find an available number. So we number them 10, 20, 30, etc., instead of just 1, 2, 3, etc.

Some of the Special Codes that can be used at the beginning of the file, after the front-matter:

  • Drawing buttons with a special graphic look:

:experimental:   ////this is here to allow btn:[]syntax used below

Example sentence indicating you can press a btn:[Save] on the user interface.
  • Setting the images base directory that will be used throughout the file:

:imagesdir: /images/en/admin

For images, this directory should be specified as an absolute path (starting with a /), not relative like ../../images. Note that this guideline is just for images, it doesn’t apply for links to pages, which should be relative.

  • Including an automatically generated Table of Contents of the sections inside this file:

  • Including an automatically generated Table of Contents of the pages in directory levels below the current page, to be used in pages that have a sub-directory. (This is a shorcode provided by our Theme).

{{% children depth="3" showhidden="true" %}}
  • Including an automatically generated List of GitHub Contributors (for the Release Notes pages). You can list an indefinte number of contributors. (This is a shortcode defined in our own site), and can serve as an example if you want to create others).

{{% ghcontributors username1 username2 %}}


In the normal text content, we follow these rules

  • Break lines approximately at the 80th column. Asciidoc ignores these line-breaks. We use them to facilitate editing the source code on a typical 80 character wide console.

  • surround paths, file names, variable names and other expressions that might be useful to copy-paste with backticks:

Source mark-up to allow easy copy of a path `/some/path` into your editor.


  • Use normal Asciidoc links to navigate between files.

  • For pages, always use relative links where possible. This is essential for translated pages to be able to use the same navigation as English pages. So your links will look like this:

Here is a link:../../admin/my-page.adoc[link for you to click!].

Use the minimum amount of .. necessary, and when backtracking through directories with .., never go above the content directory, this is never necessary.

  • For images, use the :imagesdir: as explained above, and then use a link without a path.
