Stupid Question for gm_soucenet3

I know dumb question but if someone can help NICELY that would be appreciated. I have gm_sourcenet3 but i dont know what to do with it. Can someone help?

You… play on it? O_o

whatever you download for gmod, you put it into the addons folder, if that’s what you’re asking about.

Place the dll in lua/includes/modules.
