Download Ubuntu Server 20.04 LTS onto your computer. Any other linux distribution supporting docker is also fine. This guide was written assuming
Ubuntu Server 20.04 LTS.Insert a USB Stick into your computer and create the a bootable USB Stick with the ubuntu image you just downloaded.
Open your Mini PC, plug in RAM & drives, close it, connect it to your router via ethernet cable and to a power supply. Connect a screen via HDMI, a USB keyboard, the created bootable USB Stick, fire the Mini PC up and follow the the inital setup instructions.
Update ubuntu via
sudo apt update && sudo apt upgradeIf you are using Ubuntu 20.04 LTS, install docker by running
sudo apt install docker.io. Otherwise if you are using any version besides Ubuntu 20.04, follow the official instructions to install docker.Add new user
