It took awhile to decipher the instructions, but with careful reading they are accurate and complete. It took longer than I expected, it I was able to install the bed cover without assistance. The instructions recommend two people for aligning and tightening the rail brackets, but they were not a problem. The only step that wasn't covered was how to adjust the travel to close completely, but I figured it out (just release the clutch and extend it manually, then re-engage the drive gear). I have since installed the Real Truck adjustable racks. They are easy to install and work great.
