Hi, sorry for the slow reply (just come back from new recruit boot camp)
To create a server, just open the lobby, click on the Host Game, then Create Server, then copy either Lan or Global IP address for your friend (if it's blank click Resolve first). You might have to forward port first, though. (Default port is 33331)
To join, open the lobby, click on the Join Game, then put the Host's IP then join.
The multiplayer on 0.92.0 is a bit crashy, though.
