Well, if the top has been use before, then it won't be much trouble, but if it's brand new, then expect to get sweaty.
For a new or nearly new top, Pick a nice warm sunny day. Lay the canvas out in the sun to warm up, this will allow it to stretch much easier.
Next, you'll need to find the door surrounds...the big plastic pieces. One piece for each side will have a hinge, which should have a small peg that will fit into a whole just behind the back door and there will be a C shape that will fit around the upper roll bar, kinda inside the roll bar padding. There will also be a second piece to the door surround that will overlap the first piece slightly just above the B pillar and extend to the windshield frame, also with a C clip around the rollbar. There will be 3 hand-tightened bolts that hold these in place (you will find it easiest to stand inside the vehicle or on the side steps if you have them), 2 will be significantly longer than the other, and these drop through the top of the C clip, through the roll bar and screw into the bottom of the C clip. The 3rd, shorter bolt will drop through the point at which the 2 door surrounds overlapped, and screw into the rollbar just above the B pillar.
Next, you should have 2 plastic pieces that will clip onto each side of the rear tub, just outside the tailgate. These hold the rear-window bar in place, and are not interchangeable. One end of each is closed off, and should be outboard, away from the tailgate.
