Not only that guide is really good, but also video lecture Git For Ages 4 And Up from Open Source Developers Conference
It’s a brilliant talk by a brilliant developer, and if you have some time to watch the video, I highly recommend it. But check out the very first sentence in the session description (emphasis added):
Git makes so much more sense when you understand how it really works, because it’s really a two trick pony.
Tinker Toys are the best illustration of a Git repository I’ve found. Side-by-side with issuing Git commands, we’ll build a Git repository out of kid’s toys showing what’s going on behind the scenes. Mind bending concepts like remote branching, rebase and the staging area become child’s play.
WARNING: CHOKING HAZARD - Small Parts. Not For Children Under 4 Years.
I’m totally agree with all that.
