I think that’s true for most the popular FOSS projects as great documentation is an essential ingredient for getting more users.

That said, if I have to name one, I love the docs of Plex Meta Manager (now called Kometa). It has step-by-step guides, reference pages, and even example code to help the users.

Yeah, I love Immich’s documentation. Even with my limited experience of YAML files, I was able to host a private web instance of Immich for my photo library.

FreeCAD looks like a nice project because I’m a mechanical engineer as well. So, I’ll look into it.

Thank you. I’ll look into NixOS as we need Linux documentation to welcome more users from Windows.

I’m referring to the user documentation.
