-1. Create the Kubernetes Gateway `my-hotel`:
+1. Use aws cli to create a VPC Lattice service network, with the name `my-hotel`:
    ```bash
-   kubectl apply -f examples/my-hotel-gateway.yaml
-   ```
-   ***Note***: By default, the gateway (lattice service network) is not associated with cluster's VPC.  To associate a gateway (lattice service network) to VPC, `my-hotel-gateway.yaml` includes the following annotation.
-   ```
-   apiVersion: gateway.networking.k8s.io/v1beta1
-   kind: Gateway
-   metadata:
-     name: my-hotel
-     annotations:

+    "authType": "NONE",
+    "id": "<my-hotel-sn-id>",
+    "name": "my-hotel"
+   }
    ```
-1. Verify that `my-hotel` gateway is created (this could take about five minutes):
+ 
+2.  Create the Lattice ServiceNetworkVpcAssociation between current k8s cluster VPC and `my-hotel` service network:
    ```bash
-   kubectl get gateway  
+  aws vpc-lattice create-service-network-vpc-association --service-network-identifier <my-hotel-sn-id> --vpc-identifier <k8s-cluster-vpc-id>

-   ```
-1. Once the gateway is created, find the VPC Lattice service network:
+   Wait until above ServiceNetworkVpcAssociation status change to `ACTIVE`:
    ```bash
-   kubectl get gateway my-hotel -o yaml
