+### Upgrading from the Legacy Helm Repository
+
+The Helm charts for cert-manager have historically been published to the Jetstack repository at `https://charts.jetstack.io`.
+
+This repository is still available and there are no current plans for it to change, but it is recommended to use OCI Helm charts for the latest versions of cert-manager.
+**Note that the legacy HTTP Helm repository is updated a few hours after the OCI Helm charts are published**, so you may experience a delay before new releases are available via this method.
+
+To use the legacy repository instead of the OCI registry, you need to add the Jetstack Helm repository to your local Helm client
+and use a slightly different [Helm upgrade command](https://helm.sh/docs/helm/helm_upgrade/).
