Remove the upper through bolt of the alternator, remove the bottom bolt of the alternator by unscrewing the nut. Slide the belt off pulley. Install the new alternator. Replace and tighten the bolts (You will need to use a torque wrench to tighten to the proper foot-pounds of torque. You can find the torque specs for you bolts by going to a Honda forum). Adjust the tension bolt until there is enough tension on the belt (if not enough tension you will hear the belt squeak when you stat your car).
