 # Device Update for IoT Hub
 
-
-
 As Internet of Things (IoT) solutions become increasingly widespread, it's essential that the devices forming these solutions are easy to connect and manage at scale. Device Update for Azure IoT Hub is a service that enables you to deploy over-the-air updates for your IoT devices.
 
 Device Update for IoT Hub is an end-to-end platform for publishing, distributing, and managing over-the-air updates for everything from tiny sensors to gateway-level devices. To realize the full benefits of IoT-enabled digital transformation, Device Update provides capabilities to operate, maintain, and update devices at scale, such as:
 
 - Rapid response to security threats.
 - New feature deployments to achieve business objectives.
-- No added costs for developing and maintaining an update platform.
+- Integrated updates with no added costs for developing and maintaining an update platform.
 
 ## Supported IoT devices
 
 Device Update for IoT Hub is a cloud-hosted solution for connecting virtually any device. Device Update offers optimized update deployment and streamlined operations through integration with [Azure IoT Hub](https://azure.microsoft.com/services/iot-hub/), making it easy to adopt on any existing IoT Hub-based solution, including Azure IoT Edge devices.
 
-Device Update supports a broad range of IoT operating systems, including [Eclipse ThreadX](https://github.com/eclipse-threadx) real-time operating system. For configuring, building, and deploying over-the-air updates for common microcontroller unit (MCU) class devices, Eclipse ThreadX offers [Device Update samples](https://github.com/eclipse-threadx/samples/tree/PublicPreview/ADU) codeveloped with semiconductor partners including STMicroelectronics, NXP, Renesas, and Microchip.
-
-Device Update also provides a [Raspberry Pi](device-update-raspberry-pi.md) tutorial and reference Yocto image, and a [Device Update agent simulator](device-update-simulator.md) tutorial and binary.

 Device Update agents are built and provided for various [Linux operating systems](support.md#linux-operating-systems). Device Update is also extensible via provided open-source code if you're not running Eclipse ThreadX or supported Linux platforms. You can port the agent to the distribution you're running.

 Device Update for IoT Hub supports two forms of updates, *package-based* and *image-based*. The method you choose depends on your specific use case and device environment.
 
-- Package-based updates are targeted to alter only a specific device component or application. These updates have lower bandwidth consumption and shorter download and install times, allowing for less device downtime, and avoid the overhead of creating images.

 - Image-based updates provide a high level of confidence in the device end-state, allowing easier replication between preproduction and production environments or between A/B failover models. Image-based updates avoid the challenges of managing packages and their dependencies.
