I didn't (for a couple of reasons).
-It's kind of a grey are in terms of NDA. Because on one hand, the Steamworks partner stuff is confidential (as it states on every page), but on the other hand, there are public videos on Youtube of how the process works... So I wasn't sure and decided to be on the safe side.
-Another point is that the code of the game and the programming will last for a long time, the specific process of getting the game on Steam won't. Even the game I released a couple of years ago was really different. So it's not as valuable to have an "expiring" tutorial with the live streams.
-Now with Steam Direct, if you have the dollars, they will accept it :P
-They give very explicit feedback for not approving the Store Page or the game build, so it's a lot more straightforward.
But even with that in mind, I will show the actual Steam release moment on this Friday's stream, so that should be fun! :D
