> Does git have developer documentation like haiku os, where you can quickly read the source code and know what this part or this function does. Git's Git history is very descriptive and the commits are themselves a good documentation. If the function description is not enough, you can inspect the commits related to that function/piece of code using git blame or git log. For example, I randomly picked the function `handle_path_include` from `config.c`. We can check the history of that function using: `git log -L :handle_path_include:config.c` I described more this kind of search here: https://lucasoshiro.github.io/posts-en/2023-02-13-git-debug/ I hope that it helps you!
