+
+** Please be patient while the chart is being deployed **
+
+1. Get the application URL by running these commands:
+{{- if .Values.ingress.enabled }}
+  - http{{ if .Values.ingress.tls.enabled }}s{{ end }}://{{ (index .Values.ingress.hosts 0).host }}
+{{- else if contains "NodePort" .Values.frontend.service.type }}
+  export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ include "timetracker.fullname" . }}-frontend)
+  export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
+  echo http://$NODE_IP:$NODE_PORT
+{{- else if contains "LoadBalancer" .Values.frontend.service.type }}
+  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
+        You can watch the status by running 'kubectl get --namespace {{ .Release.Namespace }} svc -w {{ include "timetracker.fullname" . }}-frontend'
+  export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ include "timetracker.fullname" . }}-frontend --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")
+  echo http://$SERVICE_IP
+{{- else if contains "ClusterIP" .Values.frontend.service.type }}
+  kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ include "timetracker.fullname" . }}-frontend 8080:80
+  echo "Visit http://127.0.0.1:8080 to use your application"
+{{- end }}
+
+2. Check the status of the pods:
+  kubectl get pods --namespace {{ .Release.Namespace }} -l "app.kubernetes.io/name={{ include "timetracker.name" . }},app.kubernetes.io/instance={{ .Release.Name }}"
+
+3. External PostgreSQL:
+  This chart requires an existing PostgreSQL database.
+  Configured connection: {{ .Values.postgresql.url }}
+
+IMPORTANT NOTES:
+- Ensure your external PostgreSQL database is reachable from within the cluster before installing.
+- Set postgresql.url in values.yaml to point to your existing database.
+- Make sure to change the OIDC configuration in values.yaml
+- Change the SESSION_SECRET from the default value for production
+- Set backend.jwt.secret to a dedicated secret in production (falls back to SESSION_SECRET if empty)
+- Configure ingress host and TLS settings for your environment
+
+OIDC Configuration Required:
+  issuerUrl:        {{ .Values.backend.oidc.issuerUrl | default "NOT SET - REQUIRED" }}
+  clientId:         {{ .Values.backend.oidc.clientId | default "NOT SET - REQUIRED" }}
+  iosRedirectUri:   {{ .Values.backend.oidc.iosRedirectUri }}
+
+JWT (iOS Bearer auth):
+  jwt.secret: {{ if .Values.backend.jwt.secret }}(set){{ else }}NOT SET - falling back to session.secret{{ end }}
