I’ve been thinking of contributing to foss projects with more than testing and bug reporting. I want to contribute to mainly open source game engines. There are a few that are mature and underrated, but lack any documentation for a user to get started. This is why I decided to do documentation, but I don’t know where or how to start.
Is there any general rule/guidelines for getting started with this ? I’m looking for anything that can help a beginner documentation writer


KDE has a lot on documentation, maybe you would get some inspiration of how this can be done: https://community.kde.org/Get_Involved/documentation
This is also a really good resource, thank you for sharing. Idk why I didn’t think about KDE apps docs before making this post. Thanks!
