Now that Steam Greenlight is closed, how do we put our games on steam?

Since Steam Greenlight is now closed, how are we supposed to put our games on steam? Is there any new plugin that we can use?

You can still put it one steam, but I have problems with showing the Steam overlay.

I also have access to the Steam username, even with the greenworks Plugin. You will just need to use an older version of NWjs.

Mine is too new, I think that's why my overlay isn't working properly.
