 # A script to perform the setup required to manually test using the supervisor on a kind cluster.
 # Assumes that you installed the apps already using hack/prepare-for-integration-tests.sh.
 #
+# This script is a little hacky to avoid setting up any kind of ingress or load balancer on Kind.
+# It uses an http proxy server and port forwarding to route the requests into the cluster.
+# This is only intended for quick manual testing of features by contributors and is not a
+# representation of how to really deploy or configure Pinniped.
+#
 # This uses the Supervisor and Concierge in the same cluster. Usually the Supervisor would be
 # deployed in one cluster while each workload cluster would have a Concierge. All the workload
 # cluster Concierge configurations would be similar to each other, all trusting the same Supervisor.
