+### Running as Standalone Controller
+
+Controller is a standard binding and can then be started independently of AAAA. When started with from build repository with
+```
+afb-daemon --port=1234 --workdir=. --roothttp=../htdocs --tracereq=common --token= --verbose --binding=./Controller-afb/afb-control-afb.so
+```
+
+Afb-Daemon only load controller bindings without search for the other binding. In this case the name of the process is not change
+to afb-audio and controller binding will search for a configuration file name 'onload-daemon-xxx.json'. This model can be used
+to implement for testing purpose or simply to act as the glue in between a UI and other binder/services.
