Finally done with all the Java tutorials and trainings that I have.. now on to learning Android development with teamtreehouse! Any suggestions at all from any of the awesome vets here??

Hi guys. I'm totaly new to git and github. I visit it from time to time but I never contributed.(i know, my description lied, a bit. i forgot to update it to say yesterday, a week ago etc.). I just created my first repo. I want to know where would be a good place to start to learn about it and know how to structure it and etc?

Question:

Going to be teaching a Minecraft class tomorrow. Easy enough, right? Problem is, I have literally zero experience with Minecraft. Anybody got pointers even for a total n00b. I think we'll basically be building stuff in Java. I figure levels? We'll be using Java to program the world seed? Again, total newb. Anybody who programmed it before want to give me a high-level view?
