+Deployment files
+================
+
+This directory contains example deployment manifests for cert-manager that can
+be used in place of the official Helm chart.
+
+This is useful if you are deploying cert-manager into an environment without
+Helm, or want to inspect a 'bare minimum' deployment.
+
+Where do these come from?
+-------------------------
+
+The manifests in these subdirectories are generated from the Helm chart
+automatically. The `values.yaml` files used to configure cert-manager can be
+found in [`hack/deploy`](../../hack/deploy/).
+
+They are automatically generated by running `./hack/update-deploy-gen.sh`.
