 Quickstart
 ==========
 
-Here is some example usage::
+If you are only retrieving data that doesn't require authorization, then you can use the unauthorized interface::
 
     import fitbit
     unauth_client = fitbit.Fitbit('<consumer_key>', '<consumer_secret>')
     # certain methods do not require user keys
     unauth_client.food_units()
 
+Here is an example of authorizing with OAuth 1.0::
+
     # You'll have to gather the user keys on your own, or try
     # ./gather_keys_cli.py <consumer_key> <consumer_secret> for development
     authd_client = fitbit.Fitbit('<consumer_key>', '<consumer_secret>', resource_owner_key='<user_key>', resource_owner_secret='<user_secret>')
     authd_client.sleep()
 
+Here is an example of authorizing with OAuth 2.0::
+
+    # You'll have to gather the tokens on your own, or use
+    # ./gather_keys_oauth2.py
+    authd_client = fitbit.Fitbit('<consumer_key>', '<consumer_secret>', oauth2=True,
+                                 access_token='<access_token>', refresh_token='<refresh_token>')
+    authd_client.sleep()
