 ## Create a route and filter to twin update notifications
 
 Azure Digital Twins instances can emit twin update events whenever a twin's state is updated. The [Azure Digital Twins tutorial: Connect an end-to-end solution](./tutorial-end-to-end.md) linked above walks through a scenario where a thermometer is used to update a temperature attribute attached to a room's twin. You'll be extending that solution by subscribing to update notifications for twins, and using that information to update our maps.
 
 This pattern reads from the room twin directly, rather than the IoT device, which gives us the flexibility to change the underlying data source for temperature without needing to update our mapping logic. For example, you can add multiple thermometers or set this room to share a thermometer with another room, all without needing to update our map logic.
 
-1. Create an Event Grid topic, which will receive events from our Azure Digital Twins instance.
-```azurecli
-az eventgrid topic create -g <your-resource-group-name> --name <your-topic-name> -l <region>
-```

+    ```azurecli
+    az eventgrid topic create -g <your-resource-group-name> --name <your-topic-name> -l <region>
+    ```
 
-2. Create an endpoint to link your Event Grid topic to Azure Digital Twins.
-```azurecli
-az dt endpoint create eventgrid --endpoint-name <Event-Grid-endpoint-name> --eventgrid-resource-group <Event-Grid-resource-group-name> --eventgrid-topic <your-Event-Grid-topic-name> -n <your-Azure-Digital-Twins-instance-name>

+    ```
 
 3. Create a route in Azure Digital Twins to send twin update events to your endpoint.
-
-```azurecli
-az dt route create -n <your-Azure-Digital-Twins-instance-name> --endpoint-name <Event-Grid-endpoint-name> --route-name <my_route> --filter "{ "endpointId": "<endpoint-ID>","filter": "type = 'Microsoft.DigitalTwins.Twin.Update'"}"

 Now that you have a hardcoded solution to updating your maps information, you can use the Azure Digital Twins graph to store all of the information necessary for updating your indoor map. This would include the stateset ID, maps subscription ID, and feature ID of each map and location respectively.
