playermodel.lua placement?

For the past month i have no idea where to put the lua files that come with playermodels. Inside of the lua files are lines that look like this

list.Set( "PlayerOptionsModel", "Tda Akita Neru Append", "models/captainbigbutt/vocaloid/neru.mdl" )
player_manager.AddValidModel( "Tda Akita Neru Append", "models/captainbigbutt/vocaloid/neru.mdl" )
player_manager.AddValidHands( "Tda Akita Neru Append", "models/captainbigbutt/vocaloid/c_arms_neru.mdl", 0, "00000000" )


You don’t need the list.Set line, you can just put the code into any file in autorun. NOT IN SERVER OR CLIENT FOLDER.

ahh okay thanks
