#1597: Git explain

[Cueball points to a computer on a desk while Ponytail and Hairy are standing further away behind an office chair.]

Cueball: This is git. It tracks collaborative work on projects through a beautiful distributed graph theory tree model.

Ponytail: Cool. How do we use it?

Cueball: No idea. Just memorize these shell commands and type them to sync up. If you get errors, save your work elsewhere, delete the project, and download a fresh copy.
