+Rocket.Chat can be accessed via port 80 on the following DNS name from within your cluster:
+
+- http://{{ template "fullname" . }}.{{ .Release.Namespace }}
+
+You can easily connect to the remote instance from your browser. Forward the webserver port to localhost:8888
+
+- kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "name" . }},release={{ .Release.Name }}" -o jsonpath='{ .items[0].metadata.name }') 8888:3000
+
+You can also connect to the container running Rocket.Chat. To open a shell session in the pod run the following:
+
+- kubectl exec -i -t --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "name" . }},release={{ .Release.Name }}" -o jsonpath='{.items[0].metadata.name}') /bin/sh
+
+To trail the logs for the Rocket.Chat pod run the following:
+
+- kubectl logs -f --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "name" . }},release={{ .Release.Name }}" -o jsonpath='{ .items[0].metadata.name }')
+
+{{- if .Values.ingress.enabled }}
+
+Rocket.Chat will be available at the URL:
+
+- http://{{ .Values.host }}
+{{ else }}
+
+To expose Rocket.Chat via an Ingress you need to set host and enable ingress.
+
+helm install --set host=chat.yourdomain.com --set ingress.enabled=true stable/rocketchat
