git has quite extensive documentation, and it is, in principle, really useful. The problem is that it suffers from what Geoffrey Pullum called "Nerdview" <https://languagelog.ldc.upenn.edu/nll/?p=276>: It is written from the perspective of the author of the program, rather than the user, and therefore it is easiest to understand if you are already thoroughly familiar with the underlying architecture of git.
