+Mixcloud OAuth2
+^^^^^^^^^^^^^^^
+
+The `Mixcloud API`_ offers support for authorization.
+To enable OAuth2 support:
+
+- Register a new application at `Mixcloud Developers`_
+
+- Add Mixcloud backend to ``AUTHENTICATION_BACKENDS`` in settings::
+
+    AUTHENTICATION_BACKENDS = (
+        ...
+        'social_auth.backends.contrib.mixcloud.MixcloudBackend',
+    )
+
+- Fill ``Client Id`` and ``Client Secret`` values in the settings::
+
+    MIXCLOUD_CLIENT_ID = ''
+    MIXCLOUD_CLIENT_SECRET = ''
+
+- Similar to the other OAuth backends you can define::
+
+    MIXCLOUD_EXTRA_DATA = [('username', 'username'), ('name', 'name'), ('pictures', 'pictures'), ('url', 'url')]
+
+as a list of tuples ``(response name, alias)`` to store user profile data on the UserSocialAuth model.
