Where do you recommend we store the pem key?

In the guide it says: /path/to/apple_push_notification.pem. Where do you recommend we store this pem key?

Using Rails, do we keep it at the application root level? Where is a sensible place?

You can store the certificate in environment variable. Rails 5.1.0 will support encrypted secrets.

Im referring to the pem file btw, not the key

There's no need to store it anywhere. You can save it to environment variable APN_CERTIFICATE_DATA and houston will fetch it automatically.
