Hello @Natcha0,
There's nothing you have to do.
It takes several business days after the tiny deposit is made for the account to be marked as "Ready".
If it's been more than a week since the deposit appeared you should contact Airbnb support.
Type "contact airbnb" in the "Search the community" box on these forum pages where you posted your question. Scroll down a little in the list of suggestions that appears and click on the "Contact Airbnb: A Community Help Guide[UPDATED]" one. That lists phone numbers and ways to contact them via Twitter or Facebook.
Steve.
