First, make sure you have the right equipment:
- Apple TV (tvOS)
- Amazon Fire Stick
Second, go here to sign up for a Home subscription. For home users on a Home subscription, there is no measurement or tracking of "hours streamed" to earn rebates or discounts on the subscription price. Play as much or as little as you like.
Third, get on your personal device and search for and download the Atmosphere app. You'll need to activate this device to get it connected to your subscription.
And that's all, folks!
