The EndeavourOS team started working on their ARM port for the distribution about two years ago. Until now, installing EndeavourOS on ARM devices required you to write the latest EndeavourOS ISO image on a microSD card, download the EndeavourOS ARM installation script, and then run the text-based installer that had several stages.
The previous ARM installer script, which is still available for unsupported devices, was for advanced users, but now anyone can try EndeavourOS on a supported ARM device (Odroid N2/N2+ and Raspberry Pi at the moment of writing this article) thanks to the new ARM installer.
