+
+* Register a new application at [Twilio Connect Api](https://www.twilio.com/user/account/connect/apps)
+
+* fill `TWILIO_CONNECT_KEY` and `TWILIO_AUTH_TOKEN` values in the settings:
+
+
+    `TWILIO_CONNECT_KEY = ''
+     TWILIO_AUTH_TOKEN = ''
+`
+
+* Add desired authentication backends to Django's `AUTHENTICATION_BACKENDS` setting:
+
+        `'social_auth.backends.contrib.twilio.TwilioBackend',`
+
+* Usage example
+	
+	`<a href="{% url socialauth_begin 'twilio' %}">Enter using Twilio</a>`
