Questions about code documentation

Hi!
Before committing to create a full fledged new thread, I wanted to know if it's ok to ask questions about documentation generation. (more specifically, C code documentation generation).

I've been battling with the infamous CMake->(Doxygen->Breathe->Sphinx) pipeline to generate docs.
Due to my immense ignorance in these field, I've spent plenty of time with increasingly scarcer materials, till I ran out of pavement and stopped.

I'm in need of some assistance/people to discuss with on the topic. Fortunately I'm beyond "how do you do this help" but I need some help to get back to the right track.

I'm talking about strictly C stuff. Most of the tools I named are primarily for C++ but I need them to behave with C. Where do I post this? Can I go to the "C" topic? Searching "documentation" in the forum brought up nothing interesting.

Thank you!
