Learning LUA

I really want to learn LUA and make my own hacks. So far all I know how to do is say things in the console and make a table. Can someone link me to a new tutorial or website for Garrys Mod 13.

That's all you need:
Lua Overview - GMod Wiki
Lua Tutorial Series - GMod Wiki
( there are even 3 hacks fully explained, go through these and edit them in some usefull ways to get started with hacking )

But this will take some time. It's really abstract at the start but you'll get used to it.
Personally, I just did some basic general lua and I am and have been learning all the gmod stuff by looking at other peoples work and learning by doing.
