Help Changing Brake Rotors!

I have a 99' prelude and am trying to figure out how to get ther rotors off. I think they may be pressed on but my uncle says i can still get them off. If anyone can tell me how please let me know....Thanks for any help in advance.

1. take off wheel
2. take of caliper.
3. Unscrew bolts
4. screw bolt in to release it from the axel if need be.
5. put new rotor on.
6. reverse steps 1-3

and pick this up.
