+Bor RPC can be accessed via port {{ .Values.services.rpc.http.port }} on the following DNS name from within your cluster:
+{{ include "bor.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
+
+To connect to Bor RPC:
+
+1. Forward the port of the pod:
+
+  $ kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l "app.kubernetes.io/name={{ include "bor.name" . }},app.kubernetes.io/instance={{ .Release.Name }}" -o jsonpath='{ .items[0].metadata.name }') {{ .Values.services.rpc.http.port }}
+
+2. Connect using the bor cli:
+
+  $ bor attach http://{{ include "bor.fullname" . }}:{{ .Values.services.rpc.http.port }}
