Android: Amazon Video on Android

I think it's a shame I feel the need to write this post, but anyway, to run Amazon Prime Video on Android you need to jump through a few hoops:

1. Install Amazon App on Play Store
2. Install Amazon Underground from:  https://www.amazon.com/underground (make sure you're not in "Request desktop" mode)
   or from: http://www.amazon.com/apps (and search for underground)
   NB: You'll need to allow apps from unknown sources to do this
3. Use Amazon Underground to search for and install Amazon Video
