Now that Mono has moved to GitHub, a number of contributors (including myself) have been somewhat lost, not knowing how to properly use Git. So today, I'm recommending a book to help all the lost souls out there get comfortable with using Git.
As many long-time programmers probably know, O'Reilly books are top notch. Most probably also would not be surprised that O'Reilly has a book covering Git: Version Control with Git: Powerful Tools and Techniques for Collaborative Software Development.
Don't let the bat scare you.
