If you bought a Linutop machine, the Linutop OS is already installed, you can skip this section.
If it's not yet installed, you are probably already running the demo system. If not, go and get it from the Linutop website.
The demo system is limited, some features can't be used, and changes are lost after reboot. To avoid this, you will need to download and install the full system on a persistent media (hard drive or USB key). This can be done from the demo system, following the installation documentation.
