 * [Prerequistes can be found here](https://repo1.dso.mil/platform-one/distros/d2iq/konvoy/konvoy/-/tree/master/docs/1.5.0#prerequisites)
+  * Konvoy clusters need a [Metrics API Endpoint](https://github.com/kubernetes/metrics#resource-metrics-api) available within the cluster to allow Horizontal Pod Autoscalers to correctly fetch pod/deployment metrics.
 * [Different Deployment Scenarios have been documented here](https://repo1.dso.mil/platform-one/distros/d2iq/konvoy/konvoy/-/tree/master/docs/1.4.4/install)
