+## Open source Python WebSockets projects
+The following projects either implement WebSockets in Python or provide
+example code you can follow to use WebSockets in your own projects.
 
+* [Autobahn](http://crossbar.io/autobahn/) uses Twisted and asyncio to
+  create the server-side WebSockets component while 
+  [AutobahnJS](https://github.com/crossbario/autobahn-js) assists on the
+  client web browser side.
 
 * The Flask-SocketIO project has a 
   [chat web application](https://github.com/miguelgrinberg/Flask-SocketIO/tree/master/example) 
   that demos sending server generated events as well as input from users
   via a text box input on a form.

 ## General WebSockets resources
+WebSockets have wide browser support and therefore many 
+[web frameworks](/web-frameworks.html) across all major programming languages
+have libraries to make creating WebSockets connections easier. The following
+resources are general guides and tutorials that provide context for the
+protocol without getting into the weeds of how to use WebSockets in
+Python.
