Thanks for reaching out! We don't actually have instructions for the REI Co-op Camp Dome 6 tent, however, we may be able to explain it to you. The three pole sections are of equal length, so as long as you have them set up going directly across the tent (grommet to grommet) you should be good to go. In terms of getting the fly set up, the trick is to look at the color of the strap on the hook of the fly and match it up with the same color of the strap on the tent body that it connects to (orange to orange, gray to gray, likely).
Hopefully this helps, let us know if you have any other questions!
