+Your username is the lowercase name shown when you login to bitly, your access token can be fetched using the following ( http://dev.bitly.com/authentication.html ):
+
+    curl -u "username:password" -X POST "https://api-ssl.bitly.com/oauth/access_token"
+
+To run the tests either export the environment variable or set it up inline before calling `nosetests`:
