+## Over The Air Updates Demo
+
+These demos demonstrate how to use the [AWS IoT Over the Air update library](https://github.com/aws/ota-for-aws-iot-embedded-sdk/tree/main) for carrying out over the air updates using MQTT and HTTP protocols for file transfer.
+
+**Note:** We recommend transitioning to the [new modular and composable OTA approach](https://freertos.org/Documentation/03-Libraries/07-Modular-over-the-air-updates/01-Over-the-air-updates) instead. To get started, see the new [OTA reference demo](https://github.com/FreeRTOS/Lab-Project-ota-example-for-AWS-IoT-Core?tab=readme-ov-file).
