+## Generated source (Helidon SE)
+
+The annotation processor will generate a `$Route` for the controller like below.
+
+Note that this class implements the Helidon Service interface, which means we can
+get all the Services and register them with Helidon `RoutingBuilder`.
+
+```
+var routes = BeanScope.builder().build().list(Service.class); 
+var routingBuilder = Routing.builder().register(routes.stream().toArray(Service[]::new));
+WebServer.builder()
+        .addMediaSupport(JacksonSupport.create())
+        .routing(routingBuilder)
+        .build()
+        .start();
+```
+### (Helidon SE) The generated WidgetController$Route.java is:
+
+```java
+package org.example.hello;

 Note that this APT processor works with both Java and Kotlin.
