Just as Peter says.
I assume you are replacing the rear sprocket. Front sprockets usually outlast rear ones by about a 3:1 ratio, so you likely won't need to touch it until 30K miles. If you get in there and remove it, but see no wear, flip it over for even more sprocket life. If you don't use an air or electric impact gun/wrench, the best way to hold the sprocket still is to put it in a higher gear (not 1st or 2nd), and put pressure on the brake pedal, while the old chain is in place.
Also, it's easiest to loosen/tighten/torque the rear sprocket bolts in the same way, with the wheel in place, rather than struggling with the wheel laying on the ground.
