  "IMPORTANT: Run your main game at least once so the saves folder gets created in your main game files for the saving per instance to work. If you are using keyboards/mice after all the instances have launched, resized and positioned correctly, press the END key once to lock the input for all instances to have their own cursor, you need to left click each mouse to make the emulated cursors appear after locking the input. Press the END key again to unlock the input when you finish playing. You can also use CTRL+Q to close Nucleus and all its instances when the input is unlocked. After the tutorial the other players will show in the game friends menu, you can connect to them there. Reduce graphics in your main game to improve performance. Xbox One/Series gamepads could have issues with background input/focus, you can use the app reWASD to covert them to xbox 360 gamepads or follow this guide: https://github.com/SplitScreen-Me/splitscreenme-www/blob/master/docs/Xboxone.md.";
