Hello, some quick questions regarding multiplayer on PrBoom
1) Do I enter /Applications/PrBoom/ In terminal?
2) After entering /Applications/PrBoom/ and the server has started what should I see?
3) How do I use the "server commands"?
4) How would one go about connecting to my server/a server?

Much thanks,
