How to create a server?

[anonymous_user_9ae3d8b0]

Hi,

I’m currently trying to network my game, but there one thing I can’t understand. I saw on many websites that to start a server, you had to use a certain command, such as: UE4Editor.exe ProjectName MapName?Listen -game.
But how do I use this command, where do I have to write it in order to work?

Thanks in advance !
