EveryPlay help!

I am just trying to get Everplay to work in my Android project, I have downloaded the EveryPlay asset from the Asset Store and imported it, but I can't see any docs on how to use it included with the Asset (which I understand if any other Asset Developer did their asset would not be allowed on the Asset Store which seems a little like double standards) so I go to the everyplay site and check the docs there and for Unity it says to get started drop the 'EveryPlay' prefab into your scene, but the asset does not include an 'EveryPlay' prefab, so added the 'EveryPlay Test' prefab in a hope I can test with that but all that does is show buttons when I hit play but they do nothing. Are there some actual correct docs for using this system? Is there another version of the Asset to download from somewhere that has the 'EveryPlay' prefab in it? Is there something else that needs installing?
