+DEPLOYMENT INFORMATION:
+{{- if .Values.persistence.enabled }}
+- Persistent storage: {{ .Values.persistence.size }} ({{ .Values.persistence.storageClass | default "default" }} storage class)
+{{- end }}
+- Health checks: Startup, liveness, and readiness probes configured

+- Service: {{ .Values.service.type }} on port {{ .Values.service.port }} -> {{ .Values.service.targetPort }}
+
+MONITORING & DEBUGGING:
+
+1. Check application status:
+   kubectl get pods -n {{ .Release.Namespace }} -l app.kubernetes.io/name={{ include "githubapp.name" . }}
+
+2. View application logs:
+   kubectl logs -f deployment/{{ include "githubapp.fullname" . }} -n {{ .Release.Namespace }}
+
+3. Access health endpoint:
+{{- if contains "ClusterIP" .Values.service.type }}
+   kubectl port-forward -n {{ .Release.Namespace }} svc/{{ include "githubapp.fullname" . }} 8080:{{ .Values.service.port }}

+   # Visit: http://$SERVICE_IP:{{ .Values.service.port }}/health
+{{- end }}
+
+4. Check configuration:
+   kubectl describe configmap/{{ include "githubapp.fullname" . }} -n {{ .Release.Namespace }}
+{{- if .Values.secrets.secretName }}
+   kubectl describe secret/{{ .Values.secrets.secretName }} -n {{ .Release.Namespace }}
