To contribute to Codeberg Documentation, the first thing you should do (if you haven't already done it) is to create your own fork of the [Codeberg/Documentation repository](https://codeberg.org/Codeberg/Documentation).
Then, for each major contribution that you want to make (e.g. for each new article), create a new branch, make your contributions and finally make a Pull Request to the Codeberg/Documentation repository. You can find the source code to all articles in the `content` directory of Codeberg
Every section and article has a unique `key`. If `parent` is set to the `key` of another section, the current article will become a child of that other section.
The other fields are `title` and `order`, where `title` is merely a display name and determines the menu entry label as well as the article's heading but has no other "technical" semantics and `order` is a number that can be used to enforce a specific order of articles (which is good for step-by-step guides such as Getting Started for example).
