+|-----------------------|------------------------------------------------------------|
+| Deploy the Agent Locally     | ```helm upgrade -i control-m-agent ./control-m-agent -n controlm -f values.yaml``` |
+| Get details                  | ```kubectl describe job “job name” This returns the pod name.``` |
+| Monitor the job’s pod        | ```kubectl get pod “pod name”```                                 |
+| Get the job output           | ```kubectl logs “pod name”```                                    |

+# A chart can be either an 'application' or a 'library' chart.

+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
