Flash games on Steam?

Hi all. It's been so long since I posted on these forums!

I have a question. Have any of you published a game on Steam? I know of some games that have been developed in Flash and were released there like VVVVVV, Intrusion 2, not sure if Super Meat Boy and some others. So, does anyone know how to do so, or what the process is. Thanks in advance!

Put your game on http://steamcommunity.com/greenlight/ and if you're popular you may have a chance.

Thanks for the reply! :) I'm a bit familiar with the Greenlight system. My question is more technically related, like do you only need to make it to a ".exe" and you're done, what API to integrate and that type of matters.
