There is no one all-inclusive article here, nor anywhere on or off the web that I know of, that will tell you everything you need to know about how to care for your iguana. Some of the articles here will overlap each other. While today you may need to zip in and out of here quickly, taking time to just save or print out one or two articles, I do hope you will return to spend some time when you have some more of it. There is a tremendous amount of information here, reflecting lots of research, observation, and discussion. Learning is a never-ending process, especially when the subject is an animal about which relatively little is known.
Iguanas are a lot of work and are very time consuming.
I figure that, if someone doesn't have the time to sit down and read through what's here to get their questions answered, they probably don't have the commitment or time to properly care for an iguana. This is an attempt to drive home the fact that green iguanas, regardless of their color or country country of origin, are considered giant lizards. If you don't want a big lizard, then don't get a green iguana. There are no dwarf species, despite what some pet stores will tell you and try to sell you. There is no way to dwarf a green iguana unless you subject it to chronic malnutrition and constant hypothermia.
