 We use the Raspberry Pi Operating System (RasPi OS) Lite, without a graphical user interface, and in the 64-bit version.

 To make this guide as universal as possible, it uses only standard Debian commands.
 As a result, it should work smoothly with Raspberry Pis while still being compatible with most other hardware platforms running Debian.
