This is my answer too. The main git book is very well written. I stopped reading just before it got into rebasing and had to pick that up from the internet due to work requirements, but the book was so solid in explaining the basics that I understood outside stuff almost immediately.

I think one thing that’ll help OP, is to learn everything on the command line. The fine grain control is worth the extra effort. I’ve hated almost all git GUIs in most IDEs because they won’t let me do weird things like grafting branches which is a very advanced concept for them but once you understand git, it is a very simple operation.
