 This tutorial uses a two device hierarchy for simplicity, pictured below. One device, the **top layer device**, represents a device at the top layer of the hierarchy, which can connect directly to the cloud. This device will also be referred to as the **parent device**. The other device, the **lower layer device**, represents a device at the lower layer of the hierarchy, which can't connect directly to the cloud. You can add more lower layer devices to represent your production environment, as needed. Devices at lower layers will also be referred to as **child devices**.

    The configuration tool creates your IoT Edge devices and sets up the parent-child relationships between them. Optionally, it creates certificates for your devices to use. If paths to deployment JSONs are provided, the tool will automatically create these deployments to your devices, but this isn't required. Finally, the tool will generate the configuration bundles for your devices and place them in the output directory. For a thorough look at the steps taken by the configuration tool, see the log file in the output directory.
