Covert game to AIR project?

Hi, just wanted to know if its possible to convert an existing game project (AS3&fla) to an AIR project?

the AIR settings on my fla is blanked out how can I convert it?

Do I need to open a new AIR project and import fla or something?
if so does anyone know how to? or any tutorials about it will help!

Thanks ^^

I would strongly advise against using AIR for your games. It opens a whole other can of worms you really don't want to be bothered with. But if you insist, you have to use the File->New -> Adobe File(Adobe AIR). After that you can continue pretty much like normal (with or without a document class if you so choose). Also, google is your friend for tutorials.
