+## How to use the Azure IoT SDKs for Python
+Devices and data sources in an IoT solution can range from a simple network-connected sensor to a powerful, standalone computing device. Devices may have limited processing capability, memory, communication bandwidth, and communication protocol support. The IoT device SDKs enable you to implement client applications for a wide variety of devices.
+* **Using PyPI package on Windows, Linux (Ubuntu) or Raspberry Pi**: the simplest way to use the Azure IoT SDK for Python to develop device apps on Windows is to leverage the PyPI package which you can install following these [instructions][PyPI-install-instructions].
+* **Clone the repository**: The repository is using [GitHub Submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules) for its dependencies. In order to automatically clone these submodules, you need to use the --recursive option as described here:
+```
+git clone --recursive https://github.com/Azure/azure-iot-sdk-python.git 
+```
+If you have downloaded the zip instead of cloning the repository, you will need to run the following command to restore submodules:
+```
+git submodule update --init --recursive
+```
+
+* **Building the libraries and working with the SDK code**: follow [these instructions][devbox-setup].
