Many great points Jyri. This course certainly is not meant to be a completely detailed introduction. At Code School we're in the middle of working on something that should be more of a step by step introduction.

However, I think there's something to be said for showing people how they can be immediately productive with a tool before really understanding everything that's going on underneath. With just a few commands someone can start using git successfully, and that's all we were trying to communicate with this tutorial.
