I've had this in a box for a year, all the parts were marked and there.  I would suggest looking for you tube video's before assembling, they helped some.  Directions were lacking, you got the idea of what to do, but there were easier ways to accomplish assembly.  I have it all set up, it looks nice, the side panels could be better, would like them to be more like the roof, but we will see.  I don't expect it to last forever, but for at least a few years.....we will see
