I made a google doc detailing how to update your gmod stuff, with some addons help as well.

There you go. I plan on turning this into a quick reference guide for any gmod update problems that arise.

I also included a list of popular addons, for quick reference, so that way you can remember what to install. I always forget to install addons whenever I reinstall gmod, and you can give this to your newer friend so they can easily get the popular stuff.

Please tell me if I missed anything as well.
