+Pi4j OS doesn't work on the Raspberry Pi 5. Instead, on a Raspberry Pi 5, do a standard install, as [described here](https://www.raspberrypi.com/software/).
+
+After starting the Raspberry Pi, you can install Java and everything you need to build Pi4J on the Raspberry Pi, using the following script:
+
+```shell
+#!/bin/bash -e
+sudo raspi-config nonint do_i2c 0
+sudo raspi-config nonint do_ssh 0
+sudo raspi-config nonint do_serial_hw 0

 This project provides pre-built versions of OS images with all you need to develop 100% pure Java applications for specific Raspberry Pi setups. They are based on the latest official [Raspberry Pi OS](https://www.raspberrypi.org/software/) and are automatically built using Packer.
