Is it the Easy camp one? If so, there will be 3 flexible poles, the 2 longest cross over to form the dome and the shortest one goes to make the door arch. The two metal king poles are to hold up the open door to make a canopy. Ours was bought new and didn't come with any instructions either!! Let me know if you need more info' if this is the right tent.
we have the same tent.....ours never quite looks like it's supposed to when up tho...lol......
