-This article describes how to use the [Azure IoT SDK for Python](https://github.com/Azure/azure-iot-sdk-python) to create device and backend service application code to receive and send cloud-to-device messages.
-
-There are two Python SDK classes that are used to send messages to and from IoT devices. Message handling methods from these classes are described in sections on this page.
-
-* The [IoTHubDeviceClient](/python/api/azure-iot-device/azure.iot.device.iothubdeviceclient) class includes methods to create a synchronous connection from a device to an Azure IoT Hub and receive messages from IoT Hub.
+## Create a device application
 
-* The [IoTHubRegistryManager](/python/api/azure-iot-hub/azure.iot.hub.iothub_registry_manager.iothubregistrymanager) class includes APIs for IoT Hub Registry Manager operations. In this article, methods from this class show how to connect to IoT Hub and send a message to a device.

 For a Python-based device application to receive cloud-to-device messages, it must connect to IoT Hub and then set up a callback message handler to process incoming messages from IoT Hub.

 This section describes how to send a cloud-to-device message. A solution backend application connects to an IoT Hub and messages are sent to IoT Hub encoded with a destination device. IoT Hub stores incoming messages to its message queue, and messages are delivered from the IoT Hub message queue to the target device.
