I seem to recall helping a friend put his up a few times.
From what I remember, all the poles are colour coded, and the colours correspond to where they should go.
The longest poles are for the dome and these cross over in the middle. Put them in first, then the next longest poles in the nearest sleeves to the dome.
The shorter poles are for the roofs of the bedrooms, and the last ones to go in are the shortest forming the outer edges of the bedrooms.
I can't remember if it has a front porch pole as well?
Start by raising the dome, then follow with the next longest poles. Its best if someone goes inside the tent to hold the poles up when raising the dome.
Put all the dome poles in first, the criss cross ones and the next ones to that, then erect the dome, and add the bedroom poles after the dome is up to cut down the weight when lifting it. You can if you want put all the poles in the correct slots before you start putting it up.
Check all the tension straps inside the tent are flat and straight and the tent should be stood up in its correct shape. Close the door and peg the rings down, and peg out the corners. Then peg out the guy lines, peg all around the edges and hang up the bedrooms
The main thing is to put all the dome poles in prior to putting the dome up, when you do put the dome up start with the longest poles first.
Hope this helps
