How do you add npc's?

I downloaded totster’s extra npc addon pack, but there aren’t specific directions on where to put them. I read the GMod wiki and did exactly what it told me to do, (take the subfolders and add it to the garrysmod folder) but to no avail. This is my first time with GMod addons so, I would genuinely appreciate help.

[EDIT]
I’m not sure, but I don’t think I have GMod 10…I bought GMod off Steam and it’s set to automatically update, or does that not give me 10?

The one you buy on Steam is the most recent.

Okay, good to know. I figured out the problem too. :smiley:
