+Lyft
+=========
+
+Lyft implements OAuth2 as its authorization service. To setup a Lyft backend:
+
+1. Register a new application via the `Lyft Developer Portal`_.
+
+2. Add the Lyft OAuth2 backend as an option in your settings::
+
+      SOCIAL_AUTH_AUTHENTICATION_BACKENDS = (
+          ...
+          'social.backends.lyft.LyftOAuth2',
+          ...
+      )
+
+3. Use the ``Client Id`` and ``Client Secret`` from the Developer Portal into your settings::
+
+      SOCIAL_AUTH_LYFT_KEY = ''
+      SOCIAL_AUTH_LYFT_SECRET = ''
+
+4. Specify the scope that your app should have access to::
+
+    SOCIAL_AUTH_LYFT_SCOPE = ['public', 'profile', 'rides.read', 'rides.request']
+
+To learn more about the API and the calls that are available, read the `Lyft API Documentation`_.
