 # Notifications
 
-DNSControl has build in support for notifications when changes are made. This allows you to post messages in team chat, or send emails when dns changes are made.
-
-Notifications are written in the [notifications package](https://github.com/StackExchange/dnscontrol/tree/main/pkg/notifications), and is a really simple interface to implement if you want to add
-new types or destinations.
+DNSControl's "notifications" feature will log `push` changes to other services in real time. Typically this is used to automatically announce DNS changes in a team chatroom.  The functionality is implemented using the open source [Shoutrrr](https://github.com/containrrr/shoutrrr) library, which knows how to communicate to many different systems.  Some additional services are provided natively, see the [notifications package](https://github.com/StackExchange/dnscontrol/tree/main/pkg/notifications).
 
 ## Configuration
 
-Notifications are set up in your credentials JSON file. They will use the `notifications` key to look for keys or configuration needed for various notification types.
+Notifications are configured in the `creds.json` file, since they often contain API keys or other secrets. The `notifications` key lists the notification service and options.

-## Future work

-Yes, this seems pretty limited right now in what it can do. We didn't want to add a bunch of notification types if nobody was going to use them. The good news is, it should
-be really simple to add more. We gladly welcome any PRs with new notification destinations. Some easy possibilities:
-
-- Email
-- Generic Webhooks
-
-Please update this documentation if you add anything.
