I just got married and I want to fix my wife papers as soon as possible. I would want to know what steps I must follow

Assuming that you are a US citizen and that your wife was admitted into the US with inspection, then you should contact an attorney asap to assit you with filing the adjustment of status paperwork. Immigration laws are constantly changing and the laws are becoming more complex. If your paperwork is not filed correctly and in order you run the risk of your wife being sent back home.
