First of all, good job on doing your reading before you bought your fish. You and your fish will thank you. I can't really explain it any better than the pinned thread, but pretty much what you do is add ammonia until it is at 4-6 ppm in the tank. Continue to do this until your ammonia is processed into nitrites then nitrates within 12 hours. Your tank is now cycled. A large (~90%) water change will likely be needed get the nitrates down. To keep it cycled, keep adding the ammonia as you were before.
This may seem kind of gross, but peeing in the tank to raise the ammonia levels will work too. I used it to cycle all of my tanks, and my uncle, who is a breeder, did it to his. If you do a fish in cycle it is just the fish pee and decaying poo that cycles the tank. All you are doing is replacing the fish and their urine with yours. It is also a bit cheaper and more convenient. There was an entire thread on this over at The Puffer Forum and it explains how this works and why it's okay.
