 # Enforcing authentication & authorization with Kuadrant AuthPolicy
 
-This guide walks you through the process of setting up a local Kubernetes cluster with Kuadrant where you will protect [Gateway API](https://gateway-api.sigs.k8s.io/) endpoints by declaring Kuadrant AuthPolicy custom resources.

-## Setup the environment
+## Prerequisites
 
-Follow this [setup doc](https://github.com/Kuadrant/kuadrant-operator/blob/main/doc/install/install-make.md) to set up your environment before continuing with this doc.
+- Kubernetes cluster with Kuadrant operator installed. See our [Getting Started](/getting-started) guide for more information.
+- [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl) command line tool.
+
+### Setup environment variables
+
+Set the following environment variables used for convenience in this tutorial:
+
+```bash
+export KUADRANT_GATEWAY_NS=api-gateway # Namespace for the example Gateway
+export KUADRANT_GATEWAY_NAME=external # Name for the example Gateway
+export KUADRANT_DEVELOPER_NS=toystore # Namespace for an example toystore app
+
+```
+
+### Create an Ingress Gateway
+
+Create the namespace the Gateway will be deployed in:
+
+```bash
+kubectl create ns ${KUADRANT_GATEWAY_NS}
+```
+
+Create a gateway using toystore as the listener hostname:
+
+```bash
+kubectl apply -f - <<EOF
+apiVersion: gateway.networking.k8s.io/v1
+kind: Gateway
+metadata:
+  name: ${KUADRANT_GATEWAY_NAME}
+  namespace: ${KUADRANT_GATEWAY_NS}
+  labels:
+    kuadrant.io/gateway: "true"
+spec:
+  gatewayClassName: istio
+  listeners:
+    - name: http
+      protocol: HTTP
+      port: 80
+      allowedRoutes:
+        namespaces:
+          from: All
+EOF
+```
+
+Check the status of the `Gateway` ensuring the gateway is Accepted and Programmed:
+
+```bash
+kubectl get gateway ${KUADRANT_GATEWAY_NAME} -n ${KUADRANT_GATEWAY_NS} -o=jsonpath='{.status.conditions[?(@.type=="Accepted")].message}{"\n"}{.status.conditions[?(@.type=="Programmed")].message}{"\n"}'
+```
 
 ### Deploy the Toy Store sample application (Persona: _App developer_)
 
+
+Create the namespace for the toystore API:
+
+```bash
+kubectl create ns ${KUADRANT_DEVELOPER_NS}
+```
+Deploy the Toy store 
 ```sh
-kubectl apply -f examples/toystore/toystore.yaml
+kubectl apply -f https://raw.githubusercontent.com/Kuadrant/kuadrant-operator/refs/heads/main/examples/toystore/toystore.yaml -n ${KUADRANT_DEVELOPER_NS}
+```
