I need help mounting The Ship

As far as I know, The Ship is a source game which, one way or another, is mountable in Garry’s Mod. I need to mount it cause of some content I need for a map. I don’t see it in the mounting tab in GMod, and I’'m not real tech savvy, but I can follow instructions. Can anyone please help? Thanks.

You will have to use the garrysmod/cfg/mount.cfg file. You’ll find instructions on how to use it inside the file.
