I made multiplayer game using UE4 2 players emulation. Whats next?

I finished up creating a multiplayer 1v1 game. All the testing was done using 2 player simulation.

What console commands would I need to use in order to make a shippable version od the game?

I was thinking in making a lobby where you can see all players looking to start a match.

But UE4 already does the connection for you so you only need to play with the replication stuff. So how to actually ship this?
