+## API Usage
+Use the API resources listed on the [REST API Documentation](http://apiwiki.twitter.com/REST+API+Documentation).
+I've currently implemented two functions, which you can see in the end of twitter_app/utils.py.
+
+**Example:**
+
+	def delete_status_message(consumer, connection, access_token, tweet_id):
+		oauth_request = request_oauth_resource(consumer, 'http://twitter.com/statuses/destroy/%s.json' % tweet_id, access_token)
+	    json = fetch_response(oauth_request, connection)
+	    return json
+
+
 ## Installation
 Add the 'twitter_app' directory somewhere on your 'PYTHONPATH', put it into 'INSTALLED_APPS' in your settings file.
 Fill in your CONSUMER_KEY and CONSUMER_SECRET either in 'twitter_app/utils.py' or in your settings file.
