 and run it through the IDE, where the entry point is the `Application` class
 (src/main/java/com/vonage/sample/serversdk/springboot/Application.java).
 
-To run the demo standalone from the command line, do `mvn install spring-boot:run`.
+To run the demo standalone from the command line, simply invoke `mvn` or `./mvnw` if you don't have it installed.
 Then open a browser to [localhost:8080](http://localhost:8080) to use the application.
 
+The default Maven goal for this project is `spring-boot:run`. To ensure a full build, you can use `mvn clean install`.
+
+On startup, your Vonage application will be updated with the webhook URLs for the demo.
+This is so that you don't have to manually set the webhook URLs on the dashboard every time you restart
+ngrok (or your preferred HTTP tunneling service). You can verify this manually by checking the application
+from [the Vonage dashboard](https://dashboard.nexmo.com/applications).

 ### Maven and Gradle
 As a demo application, this project uses Maven, however it can be adapted to work with Gradle too.
 You can use the Maven wrapper by invoking `./mvnw`. For a local installation, you can download this
