The thing I like about this that is not a presentation but more "hands on" step-by-step tutorial/guide which teaches you how git works in practice.<p>Good work Tom!
Thanks for posting this, I'd never used git before, neither looked into VCS (I'm just beginning to learn to program) and this provided a very decent understanding of the concept and how to use it!
Here is a talk by linus about git, although it isn't a tutorial.<p><a href="http://www.youtube.com/watch?v=4XpnKHJAok8" rel="nofollow">http://www.youtube.com/watch?v=4XpnKHJAok8</a>
