+go-loose has been deployed to namespace {{ .Release.Namespace }}.
+
+Access the service:
+  https://auth.urpi.be
+
+Health check:
+  curl https://auth.urpi.be/healthz
+
+PostgreSQL is deployed as a sub-chart. Credentials are in:
+  kubectl get secret {{ include "go-loose.fullname" . }}-postgresql -n {{ .Release.Namespace }} -o jsonpath='{.data.postgres-password}' | base64 -d
+
+Environment variables are stored in secret:
+  kubectl get secret {{ include "go-loose.fullname" . }}-env -n {{ .Release.Namespace }} -o yaml
+
+To update secrets (SESSION_SECRET, DATABASE_URL):
+  kubectl patch secret {{ include "go-loose.fullname" . }}-env -n {{ .Release.Namespace }} -p '{"stringData":{"GO_LOOSE_SESSION_SECRET":"new-secret"}}'
+  kubectl rollout restart deployment {{ include "go-loose.fullname" . }} -n {{ .Release.Namespace }}
+
+Default admin user is created on first startup via GO_LOOSE_LOCAL_LOGIN=true.
