+A self-hosted Dynamic DNS solution similar to DynDNS or NO-IP.
 
+You can use a hosted version at [ddns.pboehm.de](https://ddns.pboehm.de/) where you can register a
+host under the `d.pboehm.de` domain (e.g `test.d.pboehm.de`).

+**Recent Changes**
 
-<img src="screenshot.png" alt="screenshot" width="500"/>
+`ddns` has been massively restructured and refactored and now uses the PowerDNS
+[Remote Backend](https://doc.powerdns.com/md/authoritative/backend-remote/) instead
+of the [Pipe Backend](https://doc.powerdns.com/md/authoritative/backend-pipe/), which
+is far easier to deploy. It now serves both the frontend and the backend other HTTP using different ports.

-## ⚠️⚠️⚠️ Note regarding hosted version at `ddns.pboehm.de`
-
-The hosted `ddns` service with custom hosts under the `d.pboehm.de` domain (e.g `test.d.pboehm.de`) is not available
-anymore! I did not use this service for quite some time and recently there were some issues which resulted in downtime
-and expiration of all registered hosts.
