New to Gmod

Hi. I’m new to gmod and would like some advice. Like what server should i go on. What’s do. and what is DarkRP. Also, any reccomended addons/sweps/stools.

PHX and wire tool would be a good selection then you are to play online. since most of the stuff people use is from those addons.
Get Wire and PHX for sure. Most other major addons are normally dependant on certain game modes.
