Tent

Well, you should have Three (3) longer poles and Two (2) shorter. Two (2) of the longer poles will be the basic construction poles. They will basically make an "X" across the top of the tent making the four courners of the tent. The other longer pole with also go across the top of the tent and right through the "X" made by the other two (2). This will push out the sides and make is "dome-like".
The two (2) shorter poles will go on either side of the enterance. These will hold up the sides of the tent to give you more volume space on the inside. Not exactly nessasary but if you want more than one or two people to fit inside, you'll need these.
Hope I helped.
