how do you add maps to gmod?

I have been trying to add maps to gmod but for some reasson they dont show up. I use Winwar to exyract the file and then i add it to garrysmod/garrysmod/maps. It does not work. Plz help me t
and tell me what im doing wrong Thxs

Extract the .bsp into steamapps/username/garrysmod/garrysmod/maps

If that doesn’t work, you’re a pirate or shit.

make sure it’s just the bsp in the maps folder, not another folder.

pirating doesn’t affect it

Pirated shit tends not to work well with stuff it was tested with. Adding content is sure to go awry.
