+OAuth 2 Authentication
+======================
+
+Tweepy also supports OAuth 2 authentication. OAuth 2 is a method of
+authentication where an application makes API requests without the
+user context. Use this method if you just need read-only access to
+public information.
+
+Like OAuth 1a, we first register our client application and acquire
+a consumer token and secret.
+
+Then we create an AppAuthHandler instance, passing in our consumer
+token and secret::
+
+   auth = tweepy.AppAuthHandler(consumer_token, consumer_secret)
+
+With the bearer token received, we are now ready for business::
+

+       print(tweet.text)
