+### Supported Services
+
+NewPipe supports multiple services. Our [docs](https://teamnewpipe.github.io/documentation/) provide more info on how a new service can be added to the app and the extractor. Please get in touch with us if you intend to add a new one. Currently supported services are:
+
+* YouTube
+* SoundCloud \[beta\]
+* media.ccc.de \[beta\]
+* PeerTube instances \[beta\]

 ## Updates
 When a change to the NewPipe code occurs (due to either adding features or bug fixing), eventually a release will occur. These are in the format x.xx.x . In order to get this new version, you can:
  * Build a debug APK yourself. This is the fastest way to get new features on your device, but is much more complicated, so we recommend using one of the other methods.
