+### Using cord-in-a-box.sh to run the CORD fabric
+
+The `-f` option to cord-in-a-box.sh can be used to configure an ONOS
+fabric for CORD-in-a-Box.  The fabric consists of two leaf and two
+spine switches, each running a [CPqD OpenFlow software
+switch](https://github.com/CPqD/ofsoftswitch13) controlled by ONOS.
+The build process automatically generates a configuration file for the
+fabric and pushes it to ONOS.  *THIS FEATURE IS EXPERIMENTAL AND STILL
+UNDER DEVELOPMENT.*

+These VMs run software switches for the CORD fabric.  In the default configuration
+they run standard Linux bridges.  If you have chosen to run
+cord-in-a-box.sh with the experimental `-f` option, the VMs run CPqD switches controlled
+by ONOS running in the `onosfabric_xos-onos_1` container.
