Needing gamemodes?

I need some gamemodes for my server. It’s going to be a mostly private, small sever for a couple of my friends and I’m wondering where to get the game modes on the server? Like you can go to workshop and subscribe to them, but how would I go about getting the gamemode inside of my gamemodes folder and setting the game mode? I’m trying to get murder and prop hunt currently.

Sorry if I posted this in the wrong section.

Murder and Prop Hunt are both on the workshop. There’s a gamemode section, too, which might be nice to browse. Although, you find a lot of server content packs and other stuff mixed in.
