Contributing to the Documentation

Did you just have to trawl through source code to find out what something does?
Did you have to ask someone on IRC?
Have you just proudly accomplished your task despite the documentation's lack of relevant information?

Well, help us improve it!

Overview

DebOps' documentation is written in reStructuredText, built with Sphinx, hosted on readthedocs and lives in the docs/ folder of the monorepo.

You can build the documentation yourself on :ref:`your local fork<contribution_workflow>` by running :ref:`make docs<cmd_make_docs>` from your project folder.

Role documentation

The documentation for roles lives in doc/ansible/roles/.

The main entry points for role documentation are:

  • index.rst generates the top-level pages for the html documentation
  • man_index.rst generate the role manpages

To keep things uniform, sections go in the following order:

  • getting_started.rst covers initial configuration and basic usage
  • Guides, examples and anything else specific to the role's responsibilities
  • dependent.rst describes usage as a dependent role
  • Default Variables gets populated from inline markup in roles' defaults/main.yml
  • defaults-detailed.rst contains details for complex variables
  • defaults-*.rst, for roles with different types of complex variables
  • ldap-dit.rst describes the LDAP Directory Information Tree a role utilizes

The manpages follow the same order, however defaults/main and ldap-dit are omitted. They also have their own special files:

Before eveything else:

  • man_synopsis.rst provides a short hint for command line usage
  • man_description.rst provides a description of the role. This also gets included at the top of index.rst when rendering the html.

After everything else:

  • man_seealso.rst mentions any other relevant manpages or links.

Of course, due to DebOps' wide variety of roles, their documentation can also vary greatly. Plenty of roles are just fine with just a getting_started, defaults/main, and the introductory man_ stuff.

Fixing broken links

While working with the documentation, the :ref:`make links<cmd_make_links>` command can be used to spot and fix broken external links.

  • Broken links should be corrected or omitted
  • Permanent redirects should be pointed to the new addresses
  • Temporary redirects are fine and the listed links are usually desirable

Migration artifacts

Due to how the DebOps project was structured during earlier days of developent, the practice was to .. include:: an :file:`../includes/global.rst` to share references between multiple git repositories.

The current best practice is to use dynamically generated references, so if you are editing a file in the documentation and you spot this include, feel free to remove it and fix the page so it builds without it.
