It depends on how mechanical of a person you are. In simplest terms we'd unscrew the old one and put in the new one. Calibrate and then ride. Without model number or any other specifics we can only give you a general response.
For my bike, I'd change gears to the smallest gear first. Then I'd locate the screw holding the whole thing in place along the underside... unscrew. Then unhook the shift cable from the shifter. Then unthread that cable through the bike frame until I get to the derailleur. Remove / loosen the screw that holds it in place. Put the new shifter in place. Hook the cable back in. Change shifter to position of the current gear and thread the cable back through the bike to the derailleur. Slip cable back into place and tighten. Calibrate and ride...
