+You can also use WebUSB Device Firmware Upgrade to upload software directly from web browser. 
+To do that, repeat the same steps as above, but instead of using ``dfu-util``, 
+you can use `web based utility <https://github.com/devanlai/webdfu>`_.
+You will need Chrome or Edge browser as WebUSB is currently only supported in Chromium. 
+Go to ``chrome://usb-internals/`` or ``edge://usb-internals/`` and on the tab `Devices` you should see your virtual Fomu device.

+Click `Download` and in a few seconds you should see success message and observe binary running on Fomu in Renode monitor.

+For Chrome or Edge to communicate with a USB device, it must have permission to access the device.
+If Fomu is not listed on `Devices` tab, it means that the current user do not have permission to access the device. 
+Therefore you should setup udev rules to grant permission to use the USB device from a non-privileged account.
+Follow the steps described in `this tutorial <https://mithro-fomu-workshop.readthedocs.io/en/master/requirements.html#setup-udev-rules>`_.
