+## Overview
+
+Envoy Gateway supports different deployment [modes](https://gateway.envoyproxy.io/docs/tasks/operations/deployment-mode/#supported-modes),
+including a controller namespace mode(the default one) and a [gateway namespace mode](https://gateway.envoyproxy.io/docs/tasks/operations/deployment-mode/#gateway-namespace-mode).
+The conformance tests are run against both modes to ensure compatibility and functionality.
