"Git Immersion is a guided tour that walks through the fundamentals of Git, inspired by the premise that to know a thing is to do it."

A very good tutorial for Git.

"However, it's a good idea to also pre-configure the default username and e-mail for your Git installation:"

Using version 1.7.1.

"Git is a free & open source, distributed version control system designed to handle everything from small to very large projects with speed and efficiency."

Very interesting.
