EP2 Vehicles, Entities, and NPCs

How do I install Episode 2 NPCs and the Jalopy onto my server. I followed the tutorial and installed the models and everything, but how do I install entities and the like?

You need to extract all the ep2 gcf files and upload them to srcds/orangebox. Garry’s Mod will auto detect it is installed and will let the entities and vehicles be spawned.
