 but does not monitor for new clients so if you create a new client you will 
 need to restart the bus. This will be fixed in a later release.
 
+### Client Adapters 
+
+The intended use of the backbone is that multiple clients connect to the backbone 
+using adapters. An adapter handles: 
+
+- Authentication 
+- Sending and receiving over the backbone API 
+- Transforming messages between local formats and the backbone message formats
+
+We have implemented the following template client adapters: 
+
+- [Javascript](https://git.noc.ac.uk/communications-backbone-system/backbone-adapter-javascript)
+- [Python](https://git.noc.ac.uk/communications-backbone-system/backbone-adapter-python)
+
+If you need to port the adapter to another language please contact us. 
+
+The adapters can be installed as packages and sub-classed as required for your 
+client application.
+
+For install and usage instructions for the adapters see the READMEs.
