new guy question please help

I am trying to install addons for gmod but with all the videos i see they all have an addon file I dont have this file this might sound stupid but do i have to make one by myself :stuck_out_tongue: thanks for the help

can you re-word this i dont seem to understand this question

I Dont have an addon file to put my addons in… what do i do.

oh, yeah, you just make an “addons” folder and put stuff in there.
The same principle works for “gamemodes” if you download any of that stuff
