-You can also connect at `localhost:1883` and send messages to zilla with [mosquitto](https://mosquitto.org/download/) or your own v5 client.
+### Publish your own messages
 
-```bash:no-line-numbers
-mosquitto_pub -V '5' -t 'zilla-quickstart' -m 'Hello, world' -d
-```
+Using your own topic name you can subscribe and publish an MQTT message.
 
-The Postman collection exposes the `iot-messages` and `iot-retained` topics using the [http-kafka](../../reference/config/bindings/binding-http-kafka.md) binding and a stream of all messages using the [sse-kafka](../../reference/config/bindings/binding-sse-kafka.md) binding
+Setting the `retain` flag to true on to your topic will send that message to the `retained` Kafka topic. After those messages are published a new subscription will get the last message sent for that topic.
