"Coding by example" guide?
 

I'm looking at strating coding my first addon to assist my guild instanceing (kinda like CT RaidTracker, but less features and slightly different purpose).

Problem is that I'm a total nub on LUA-coding and need some basic guidance on how to start coding.

So my question is wether anyone here know of some good coding-guides that can help me.. What did you use to get yourself started on LUA-coding?
