 ### See Messages in Kafka UI
 
 Open [Kafka UI](http://localhost:8080/) -> `Topics` -> `aidbox-forms` -> `messages` and review the `QuestionnaireResponse` that was created after submitting the form.
+
+## Demo
+
+A fully deployed and configured [Aidbox](https://subscriptions.hz.aidbox.dev/) instance with [Kafka](https://kafka-ui-subscriptions.hz.aidbox.dev/) is available for you to explore how Aidbox's SubscriptionTopic works. The SubscriptionTopic in Aidbox is set up to send `QuestionnaireResponse` events in the `completed` status to Kafka.
+
+To try it out:
+
+1. Open the [Aidbox](https://subscriptions.hz.aidbox.dev/) link.
+2. Log in using the username `subscriptions-demo` and the password `password`.
+3. Navigate to [Aidbox Forms](https://subscriptions.hz.aidbox.dev/ui/sdc).
+4. Click on `share`, then select `attach`, copy the link, and open it.
+5. Fill out the form and submit it to create a `QuestionnaireResponse`.
+6. Finally, open the [Kafka UI](https://kafka-ui-subscriptions.hz.aidbox.dev/ui/clusters/local/all-topics/aidbox-forms/messages?filterQueryType=STRING_CONTAINS&attempt=2&limit=100&page=0&seekDirection=BACKWARD&keySerde=String&valueSerde=String&seekType=LATEST) to view your `QuestionnaireResponse` in the Kafka messages.
