Collectible Card Game Headquarters

Hi all,
Is there a reference somewhere that tells me how to install the game and then apply the patches?
I scanned the forums and the wiki but couldn't find that. I found lots of releases, but I don't know what to do with them. Sorry if I'm being dense.

Is a Steam install the way to go, or is there an alternative?
Thanks
