+⚠️ WARNING: New default private key rotation policy for Certificate resources.
+The default private key rotation policy for Certificate resources was
+changed to `Always` in cert-manager >= v1.18.0.
+Learn more in the [1.18 release notes](https://cert-manager.io/docs/releases/release-notes/release-notes-1.18).
+
+cert-manager {{ .Chart.AppVersion }} has been deployed successfully!
+
+In order to begin issuing certificates, you will need to set up a ClusterIssuer
+or Issuer resource (for example, by creating a 'letsencrypt-staging' issuer).
+
+More information on the different types of issuers and how to configure them
+can be found in our documentation:
+
+https://cert-manager.io/docs/configuration/
+
+For information on how to configure cert-manager to automatically provision
+Certificates for Ingress resources, take a look at the `ingress-shim`
+documentation:
