There is the readme file in there.

I'm not goint to deduct any "brownie points" but you should show your controls and a how to play somewhere in your game as readme's are still great but not everyone will see them as its something more left in the past. You could add controls to the game page to counteract this as the game page would be perfect to display any relevent infomation about the game.
