 Usage
 ------------
-In Flowroute's approach to building the Python library v3, HTTP requests are handled by controllers named after the API resources they represent: **Numbers**, **Routes**, and **Messages**. These controllers contain the methods used to perform messaging, number management, and route management within the Python library.
+In Flowroute's approach to building the Python library v3, HTTP requests are handled by controllers named after the API resources they represent: **Numbers**, **Routes**, **E911s**, **CNAMs**, and **Messages**. These controllers contain the methods used to perform messaging, number management, route management, E911 address management, and CNAM record management  within the Python library.
