 It can be convenient to write a shell script (or an alias) to automatically insert the necessary options.
 
+The minimal configuration file required must specify the openrc file to use (using in-container path), the PCI addresses of the 2 NIC ports to use
+for generating traffic and the line rate (in each direction) of each of these 2 interfaces.
+
+Here is an example of mimimal configuration where:
+the openrc file is located on the host current directory which is mapped under /tmp/nfvbench in the container (this is achieved using -v $PWD:/tmp/nfvbench)
+the 2 NIC ports to use for generating traffic have the PCI addresses "04:00.0" and "04:00.1"

+                        {
+                            "pci": "04:00.0",
+                            "port": 0,

+                        {
+                            "pci": "04:00.1",
+                            "port": 1,
+                        }

+                }
+            ]
+        }
+    }
+
+The other options in the minimal configuration must be present and must have the same values as above.

 3. Start the Docker container
 -----------------------------
 As for any Docker container, you can execute NFVbench measurement sessions using a temporary container ("docker run" - which exits after each NFVbench run)
