+Subsonic API
+============
+
+Funkwhale implements a subset of the `Subsonic API <http://www.subsonic.org/pages/api.jsp>`_ that makes it compatible
+with various apps in the Subsonic ecosystem (See :doc:`../users/apps`).
+
+Supported endpoints
+-------------------
+
+We seek the best compatibility with existing apps and wil eventually implement
+all endpoints that match Funkwhale's feature set. However, the current implementation
+do not include folder-based endpoints, as it does not match our internal model at all
+and will require substantial effort to emulate.
+
+We'll try to keep this list up-to-date, but you can also browse `the relevant code
+<https://code.eliotberriot.com/funkwhale/funkwhale/blob/develop/api/funkwhale_api/subsonic/views.py>`_
+if needed.
+
+As of today, the following endpoints are implemented:
+
+- createPlaylist
+- deletePlaylist
+- getAlbum
+- getAlbumList2
+- getArtist
+- getArtistInfo2
+- getArtists
+- getAvatar
+- getCoverArt
+- getIndexes
+- getLicense
+- getMusicFolders
+- getPlaylist
+- getPlaylists
+- getRandomSongs
+- getSong
+- getStarred
+- getStarred2
+- getUser
+- ping
+- scrobble
+- search3
+- star
+- stream
+- unstar
+- updatePlaylist
+
+We support both XML and JSON formats for all those endpoints.
+
+Additional properties
+---------------------
+
+Regardless of the endpoints, we always return those additional properties
+in our payload, which you can use to adapt your client behaviour if needed:
+
+.. code-block:: json
+
+    {
+        "subsonic-response": {
+            ...
+            "type": "funkwhale",
+            "funkwhaleVersion": "0.17"
+        }
+    }
+
+Testing a Subsonic app
+----------------------
+
+We maintain a demo server at https://demo.funkwhale.audio/, which you can use for
+your tests. Example with the ping endpoint: https://demo.funkwhale.audio/rest/ping.view?f=json
