 To run the test against your cluster, first export the ``CLUSTER_DIR``
 environment variable with the location of your cluster config directory (replace
-``stackspin.example.org`` with your cluster name):
+``stackspin.example.org`` with your cluster name). Then export the
+``KUBECONFIG`` variable that lets ``kubectl`` talk to your cluster. Thirdly,
+we'll export a variable that contains the password for the Prometheus HTTP
+endpoint.
 
 .. code:: bash
