Please note: the mod is in early alpha stage. You need a decent level of computer knowledge to install / set it up at the moment. It is not released for production, just for testing by experienced users.

If you want to 'just play multiplayer', this is not for you. It's only a pre-alpha test build.

The debug versions output log files and stacktraces. This data is helpful to fix bugs and improve the mod. Please always attach log files to your problem reports (reproduce your problem with the debug version).
