need help with addons

so ive recenly downloaded garrys mod and am pretty unsure how to do clso to anything. ive downloaded a few addons and im not sure how to get them to work in-game. can someone help me out here?

Just go to my my computer-C:-prorgram files-steam-steamaps-YOUR STEAM ID-garrysmod-garrysmod-addons. Put the addon folders there and there ya go.

Edit: Never type exec lab in your console. It’s bad.

Just like above but go my computer-C:-prorgram files-steam-steamaps-YOUR STEAM ID-garrysmod-garrysmod- Maps, if it is a map you have downloaded.

@forestraptor what happens when you type exec lab in to the console??

people DIE!
