[Tutorial] Well ... :)

[rubyFeedback]

This may be a bit much to ask, because people don't have much time available, I suppose ...

... but I think I am not the only one who thinks that it would be nice if someone could explain the code too.

This does NOT have to be to every minute details, mind you; just a single high quality document perhaps that introduces to the essentials, sort of like a semi-detailed overview, and linked in from the main README.md. (Sorry if I write this in the wrong github repository; I don't know who is running what really ... I am only interested in reading some explanations how these things did work. Makes watching these old videos more fun too!)
