Online Multiplayer powered through Xbox

Yo, I’m gonna keep this quick as its a simple questino. I recently downloaded UE4 (today lol) and am making a little game just so me and my friends can play. How do I make it so we can all play together on the xbox?

you have to register as an xbox developer, and to do that you need to prove to microsoft that you are able to, and plan to create a quality game. they don’t just release the DevKit to anyone to play around with, plus you have to sign NDA’s.
