+If you are looking for information on how to deploy the DCN DT, then
+please see the
+[DCN README in the examples directory](../../examples/dt/dcn/README.md).
+
+This directory, `architecture/dt/dcn/`, exists so that the
+[kustomization.yaml](../../examples/dt/dcn/kustomization.yaml)
+in the examples directory for the DCN DT, reference it by path as a
+component. Its contents are likely uninteresting unless you want to
+understand how kustomize was implemented in this repository.
