I don't think I've ever seen one. It's one of those things, that if you can't pull it out of the bag at 0'dark 30 set it up, for the first time seeing it, and be cutting zzzzzs in 15 minutes, you should be in a Motel 6. It is very simple.
Same as any other tent for maint. Clean and dry when put away. Fold it to the length of the bag, roll it up and stuff it into the bag like a sausage.
