Existing docs (to be reviewed & updated):

• https://aerogear.org/docs/specs/
• https://aerogear.org/docs/guides/aerogear-android/push/
• https://aerogear.org/docs/unifiedpush/aerogear-push-ios/guides/
• https://aerogear.org/docs/unifiedpush/aerogear-push-android/guides/

As part of this task I'd recommend:

• fixing/updating any minor docs things
• creating follow up issues in this Epic for larger docs updates or missing content
