+# MapProxy Kubernetes Kustomize overlay configuration
+
+Declarative management of MapProxy Kubernetes resources using Kustomize.
+
+# How to use
+
+Within an overlay directory, create a `config.yaml` file to configure the
+proxied tile layers.
+
+Review the built resource output using `kustomize`:
+
+```bash
+kustomize build kustomize/overlays/uat/ | less
+```
+
+Run `kubectl` with the `-k` flag to generate resources for a given overlay:
+
+```bash
+kubectl apply -k kustomize/overlays/uat --namespace sss --dry-run=client
+```
