Booting a Raspberry Pi 3 from an SSD connected via a USB adapter. Includes demo of the Etcher image writer, which is available at: https://etcher.io/
Please note that the process shown in this video remains experimental and hence should be undertaken at your own risk.
Please also note that you can boot a Raspberry Pi 3 Model B+ from USB without having to go through the process shown in this video. Only the first Raspberry Pi 3 needs re-configuring for USB boot. The Pi 3 B+ is pre-configured for USB boot.
