Here is an explanation on how to set up a lobby:

-All players set up a unique nick and go to server

[HOST] -1 player creates the lobby that everyone will join by double clicking [Create lobby] The lobby creator has control over the match settings, score to win, map to play, and some balance related things.

[GUESTS] -After the host creates a lobby, the other players double click the nick of the host on the lobby list to join that lobby if no lobbies show up, this either means that there are no lobbies, or, that the lobby was created after you entered the screen, double clicking [Refresh list] will load the list again

Congrats! you have joined a lobby Now the host can start the game.

Up to 5 players can play together, it is recommended to play with 4 or 5 players for a more balanced experience, so make sure to invite some friends or people on discord ^.^
