 Follow the same steps as for **Enable Snapshot Debugger**, but switch both switches for Snapshot Debugger to **Off**.
 We recommend that you have Snapshot Debugger enabled on all your apps to ease diagnostics of application exceptions.
 
+## Azure Resource Manager template
+
+For an Azure App Service, you can set app settings in an Azure Resource Manager template to enable Snapshot Debugger and Profiler. You add a config resource that contains the app settings as a child resource of the website:
+
+```json
+{
+  "apiVersion": "2015-08-01",
+  "name": "[parameters('webSiteName')]",
+  "type": "Microsoft.Web/sites",
+  "location": "[resourceGroup().location]",
+  "dependsOn": [
+    "[variables('hostingPlanName')]"
+  ],
+  "tags": { 
+    "[concat('hidden-related:', resourceId('Microsoft.Web/serverfarms', variables('hostingPlanName')))]": "empty",
+    "displayName": "Website"
+  },
+  "properties": {
+    "name": "[parameters('webSiteName')]",
+    "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', variables('hostingPlanName'))]"
+  },
+  "resources": [
+    {
+      "apiVersion": "2015-08-01",
+      "name": "appsettings",
+      "type": "config",
+      "dependsOn": [
+        "[parameters('webSiteName')]",
+        "[concat('AppInsights', parameters('webSiteName'))]"
+      ],
+      "properties": {
+        "APPINSIGHTS_INSTRUMENTATIONKEY": "[reference(resourceId('Microsoft.Insights/components', concat('AppInsights', parameters('webSiteName'))), '2014-04-01').InstrumentationKey]",
+        "APPINSIGHTS_PROFILERFEATURE_VERSION": "1.0.0",
+        "APPINSIGHTS_SNAPSHOTFEATURE_VERSION": "1.0.0",

+        "ApplicationInsightsAgent_EXTENSION_VERSION": "~2"
+      }
+    }
+  ]
+},
+```
+
 ## Next steps
 
 - Generate traffic to your application that can trigger an exception. Then, wait 10 to 15 minutes for snapshots to be sent to the Application Insights instance.
