Updated Lua Tutorial For Gmod13

I can’t seem to find an updated Lua tutorial to Gmod 13 so I can start working on some of my own projects, I already know Lua, I just need to know Gmod’s custom functions.

Here are the changes from GM12 to GM13: https://docs.google.com/document/d/1khSuIYrAMkqXu7wlH5YRJNwz6hOH6Xqi5lqBhE3x6gA/edit?pli=1#

Thanks, appreciate it.
