+## Dialogue

+The `alexa-app` library has special handling for enabling Alexa to handle Dialogue directly. To
+configure `alexa-app` to delegate dialogue to Alexa, enable the handling
+per-intent via the schema:
+
+```javascript
+app.intent("sampleIntent", {
+    "dialogue": {
+      type: "delegate"
+    },
+    "slots": { ... },
+    "utterances": [ ... ],

+// check if the intent's dialogue is STARTED

 ## Error Handling
 
 When handler functions throw exceptions, they will trigger a rejection in the promise chain. If the response has not already been sent, `.post` will be triggered which will allow you to force a successful response. If `post` does not alter the response, then a failed response will be sent. You can use this to throw an exception to or call `return response.fail("message")` to force a failure, but this *does not* generate a response compatible with Alexa.
