IMO this should land as a new file after https://mobile-docs.netlify.com/aerogear/latest/push-notifications/#handling-push-notifications-push

that is, a new entry in https://github.com/aerogear/mobile-docs/blob/master/modules/ROOT/pages/push-notifications.adoc

= Modifying your Push Notification variant
You can modify the configuration of the push notification variant using the Unified Push Admin UI.
However note that changing any of the following values require that you update `mobile-services.json` file manually:

• list
• of
• items

To update your `mobile-services.json` file:

. do this
. do that

Note: Once you have changed the `mobile-services.json` file manually, you cannot later use any of the procedures documented. Instead, you must note any changes that are instigated by binding or unbinding from services and make all the changes manually.

Wei Li am i missing anything in this outline, can we fill it out with some of the items that would provoke the user changing to manually updating mobile-services.json?
