+Also, you must have a "test cell" as this test leverages the bash scripts that are used to install the controller.
+To override any variables used in the suite, you can do so from the command line. eg "-v ONOS_HOME:/opt/onos"
 Usage eg. "pybot -v USER_HOME:/home/fedora -v ONOS_HOME:/opt/onos -v start:10 -v end:30 -v increments:10 ScalePOC.robot"
 
 After the test complete, three files will be generate from where you issued the "pybot" command. The "report.html" file will be your results!
