How do you raise a Desert Iguana?

I've researched and researched and I've found nothing on how to care for a Desert Iguana as a pet. Can someone who has/had a Desert Iguana give me all the info I need to know? Or can someone direct to me a good web site with accurate pet care info on caring for a Desert Iguana. I have a Leopard Gecko, and I know that it only eats at night because it is nocturnal. Even the little info like that would be much appreciated!
