+### Create Gateway
+Create a `Gateway` resource for this guide:
+
+```sh
+kubectl apply -f -<<EOF
+apiVersion: gateway.networking.k8s.io/v1
+kind: Gateway
+metadata:
+  name: kuadrant-ingressgateway
+spec:
+  gatewayClassName: istio
+  listeners:
+  - name: http
+    protocol: HTTP
+    port: 80
+    allowedRoutes:
+      namespaces:
+        from: Same
+EOF
+```
+The `Gateway` resource created above uses Istio as the gateway provider. For Envoy Gateway, use the Envoy Gateway `GatewayClass` as the `gatewayClassName`.
