+## 🆕 Terraform version of `kubeapply`
+
+We recently open-sourced a Terraform-provider-based version of this tool; see the
+[repository](https://github.com/segmentio/terraform-provider-kubeapply) and
+[documentation in the Terraform registry](https://registry.terraform.io/providers/segmentio/kubeapply/latest/docs) for more details.
+
+Note that the Terraform version has slightly different interfaces and assumptions (e.g., no
+support for Helm charts), so it's not a drop-in replacement for the tooling here, but it follows
+the same general flow and configuration philosophy.
