+# Consume MQRFH2 headers
+
+This example demonstrates how to consume messages with MQRFH2 header from an IBM MQ queue.
+
+## Prerequisites
+
+### 1. Setup IBM MQ server
+
+Refer to the [Setup Guide](https://dev-central.ballerina.io/ballerinax/ibm.ibmmq/latest#setup-guide) to set up the IBM MQ server locally.
+
+### 2. Configuration
+
+Update IBM MQ related configurations in `Config.toml` in the example directory:
+
+```toml
+queueManagerName = "<queue-manager-name>"
+host = "<host>"
+port = <port>
+channel = "<ibm-mq-channel>"
+userID = "<user-ID>"
+password = "<password>"
+queueName = "<queue-name>"
+```
+
+## Run the Example
+
+Execute the following command to run the example:
+
+```bash
+bal run
+```
