+-------------------------------------------------------------------------------
+ WARNING
+
+    By specifying "serviceType=LoadBalancer" and not specifying "auth.enabled=true"
+    you have most likely exposed the Memcached service externally without any
+    authentication mechanism.
+
+    For security reasons, we strongly suggest that you switch to "ClusterIP" or
+    "NodePort". As alternative, you can also specify valid credentials using the
+    "auth.username" and "auth.password" parameters.
+

+** Please be patient while the chart is being deployed **
+
+Memcached can be accessed via port {{ .Values.service.ports.memcached }} on the following DNS name from within your cluster:
+
+    {{ include "common.names.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}
+
+{{- if eq .Values.architecture "high-availability" }}
+
+Please see https://github.com/memcached/memcached/wiki/ConfiguringClient to understand the Memcached model and need for client-based consistent hashing.
+You might also want to consider more advanced routing/replication approaches with mcrouter: https://github.com/facebook/mcrouter/wiki/Replicated-pools-setup
