  "IMPORTANT: Make sure no two players have names that are the same length AND start and end with the same characters. Launch the game outside of nucleus, disable fullscreen, and set your desired graphical settings before using this handler.\n\nAfter all instances have resized, repositioned, and refreshed you need to use the mouse to click on a menu option for each gamepad player and press END to lock input and grant each player control. You may want to mute the music in all but one instance.\n\nHost a public match with one instance and join with the rest.\n\nPress the END key again to unlock the input. You can also use CTRL+Q to close Nucleus and all its instances.";
