Help with HEADSPACK addon please?

Hey guys,
for a while now I’ve been trying to get the headspack addon to work. But Every time I try I never come up in my Garrys mod menus here’s the list of games I have

Half-Life 2
Portal
Half-Life
Counter Strike: source
Garrys Mod

Can someone please tell me how to install Headspack.

Any help is appreciated
Thanks
Seb

It doesn’t have a spawnlist. You need to use ‘browse’ to find it.

Ok that’s the spawnlist problem done, but where do I put it? like which files go where?

If the download had in the root models and materials, put both in the Garry’s Mod folder

If it’s just a folder “headspack” or else, install it in addons
