To use an IoT Edge device, it needs to be registered in IoT Hub.
### Task - register an IoT Edge device
1. Create an IoT Hub in the `fruit-quality-detector` resource group. Give it a unique name based around `fruit-quality-detector`.
1. Register an IoT Edge device called `fruit-quality-detector-edge` in your IoT Hub. The command to do this is similar to the one used to register a non-edge device, except you pass the `--edge-enabled` flag.
```sh
az iot hub device-identity create --edge-enabled \
--device-id fruit-quality-detector-edge \
--hub-name <hub_name>
```
Replace `<hub_name>` with the name of your IoT Hub.
1. Get the connection string for your device using the following command:
```sh
az iot hub device-identity connection-string show --device-id fruit-quality-detector-edge \
--output table \
--hub-name <hub_name>
```
Replace `<hub_name>` with the name of your IoT Hub.
Take a copy of the connection string that is shown in the output.
## Set up an IoT Edge device
### Task - set up an IoT Edge device
The IoT Edge runtime only runs Linux containers. It can be run on Linux, or on Windows using Linux Virtual Machines.
* If you are using a Raspberry Pi as your IoT device, then this runs a supported version of Linux and can host the IoT Edge runtime. Follow the [Install Azure IoT Edge for Linux guide on Microsoft docs](https://docs.microsoft.com/azure/iot-edge/how-to-install-iot-edge?WT.mc_id=academic-17441-jabenn) to install IoT Edge and set the connection string.
> 💁 Remember, Raspberry Pi OS is a variant of Debian Linux.
* If you are not using a Raspberry Pi, but have a Linux computer, you can run the IoT Edge runtime. Follow the [Install Azure IoT Edge for Linux guide on Microsoft docs](https://docs.microsoft.com/azure/iot-edge/how-to-install-iot-edge?WT.mc_id=academic-17441-jabenn) to install IoT Edge and set the connection string.
* If you are using Windows, you can install the IoT Edge runtime in a Linux Virtual Machine by following the [Install and start the IoT Edge runtime section of the Deploy your first IoT Edge module to a Windows device quickstart on Microsoft docs](https://docs.microsoft.com/azure/iot-edge/quickstart?WT.mc_id=academic-17441-jabenn#install-and-start-the-iot-edge-runtime). You can stop when you reach the *Deploy a module* section.
* If you are using macOS, you can create a virtual machine (VM) in the cloud to use for your IoT Edge device. These are computers you can create in the cloud and access over the internet. You can create a Linux VM that has IoT Edge installed. Follow the [Create a virtual machine running IoT Edge guide](vm-iotedge.md) for instructions on how to do this.
