+Patroni can be accessed via port 5432 on the following DNS name from within your cluster:
+{{ template "patroni.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
+
+To get your password for superuser run:
+
+    # superuser password
+    PGPASSWORD_SUPERUSER=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "patroni.fullname" . }} -o jsonpath="{.data.password-superuser}" | base64 --decode)

+
+To connect to your database:
+
+1. Run a postgres pod and connect using the psql cli:
+    # login as superuser
+    kubectl run -i --tty --rm psql --image=postgres \
+      --env "PGPASSWORD=$PGPASSWORD_SUPERUSER" \
