 == Using the Container
 
 A container is available that contains all the tests; it is pre-configured to do
-a long duration test run. The only input needed is a kubeconfig for the cluster

+You can run the container using the example below.
 
 The container requires a minimum of 4 CPU cores and 8Gig of RAM to run
