Lua Scripting

If you don't know anything about scripting, I prefer you start by opening the "Beginner Tutorial." Read them in order. As in 1, 2, 3, 4, 5, and so on. If you know the basics of scripting, start with Intermediate. If your just past the intermediate level, start with advanced. Once you done reading all of it, you should try the Wiki. It will help you on a lot more than this covers.
