+
+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 \[beta\]
+
+## 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.
+ * Download the APK from [releases](https://github.com/TeamNewPipe/NewPipe/releases) and install it.
+ * Update via F-droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, then push the update to users.
+
+When you install an APK from one of these options, it will be incompatible with an APK from one of the other options. This is due to different signing keys being used. Signing keys help ensure that a user isn't tricked into installing a malicious update to an app, and are independent. F-Droid and GitHub use different signing keys, and building an APK debug excludes a key. The signing key issue is being discussed in issue [#1981](https://github.com/TeamNewPipe/NewPipe/issues/1981), and may be fixed by setting up our own repository on F-Droid.
+
+In the meanwhile, if you want to switch sources for some reason (e.g. NewPipe's core functionality was broken and F-Droid doesn't have the update yet), we recommend following this procedure:
+1. Back up your data via "Settings>Content>Export Database" so you keep your history, subscriptions, and playlists
+2. Uninstall NewPipe
+3. Download the APK from the new source and install it
+4. Import the data from step 1 via "Settings>Content>Import Database"
