help with addons please?

i have free version of gmod 9 and i dont know how to put addons on. can someone please explain. soory im a gmod noob just got last night. oh and i know steam/steamapps/user/garrysmod/garrysmod/addons but since my gmod was free mine looks like steam/steamapps/sourcemod/gmod9. any way to put on addons?

There’s no support for GMod 9 and most of the game doesn’t work due to recent Source updates I believe. You’re in the wrong section and you seem to have no idea how to properly ask for help. Go to Help & Support once you buy the actual game.
