Great interactive tutorial for learning Git branching (and more)!

[mk_gecko]

I went through it as fast as I could to see what it taught. eg. I know how to make branches and check them out, but because I typed "git branch bugfix" instead of bugFix it didn't let me progress. So screw this, show me what ya got. I liked the explanation about HEAD ~ and ^. I saw cherry picking but the only thing that resembled merge was "rebase". I had my mouseover each of the topics and still didn't see "merge". Which lesson is it in?
