NVidia “GEForce Now”, the cloud gaming service, is kind of strange. They take free to play games and put them on their servers, often without asking the publisher. Most of the news about GEForce Now is about publishers demanding their games be taken down.

How does the other side work, though? What if you want to put something on GeForce Now? How do you do that? Is there an organized process? Some developer portal? Do you have to pay them? Or what?
