Documentation guidelines

This page describes the rules to follow if you want to contribute to Godot Engine by writing or reviewing documentation, or by translating existing documentation.

How to contribute

Creating or modifying documentation pages is mainly done via the godot-docs GitHub repository. The HTML (or PDF and EPUB) documentation is generated from the .rst files (reStructuredText markup language) in that repository. Modifying those pages in a pull request and getting it merged will trigger a rebuild of the online documentation.

For details on Git usage and the pull request workflow, please refer to the Pull request workflow page. Most of what it describes regarding the main godotengine/godot repository is also valid for the docs repository.

The README.md file contains all the information you need to get you started, please read it. In particular, it contains some tips and tricks and links to reference documentation about the reStructuredText markup language.

Warning

If you want to edit the API reference, please note that it should not be done in the godot-docs repository. Instead, you should edit the doc/classes/* XML files of Godot’s main repository. These files are then later used to generate the in-editor documentation as well as the API reference of the online docs.

What makes good documentation?

Documentation should be well written in plain English, using well-formed sentences and various levels of sections and subsections. It should be clear and objective.

We differentiate tutorial pages from other documentation pages by these definitions:

  • Tutorial: a page aiming at explaining how to use one or more concepts in the editor or scripts in order to achieve a specific goal with a learning purpose (e.g. “Making a simple 2d Pong game”, “Applying forces to an object”).
  • Documentation: a page describing precisely one and only one concept at a time, if possible exhaustively (e.g. the list of methods of the Sprite class, or an overview of the input management in Godot).

You are free to write the kind of documentation you wish, as long as you respect the following rules (and the ones on the repo). In particular, you can contribute tutorials in the “Community” section of the docs, where they could be merged relatively easily, improved by other contributors and eventually moved to an “official” section if relevant.

Titles

Always begin pages with their title and a Sphinx reference name:

.. _doc_insert_your_title_here:

Insert your title here
======================

The reference allows to link to this page using the :ref: format, e.g. :ref:`doc_insert_your_title_here` would link to the above example page (note the lack of leading underscore in the reference).

Also, avoid American CamelCase titles: title’s first word should begin with a capitalized letter, and every following word should not. Thus, this is a good example:

  • Insert your title here

And this is a bad example:

  • Insert Your Title Here

Only project, people and node class names should have capitalized first letter.

Translating existing pages

For the moment, only English documentation is provided. We want to propose localized documentation in the future, but this is not a priority for now. Indeed, since the English documentation is still evolving a lot as the community improves it and make it more professional, we prefer that translators do not spend too much time on it, as their translated documentation might quickly grow out of sync with the original.

When the English documentation is ready for translations, we will provide tools to simplify the work of translators by tracking changes to the English docs that they should translate on their end.
