The goal of this is to prepare the 3 SD cards with a base installation of the Raspberry Pi Lite OS. Raspberry Pi OS us a variant of Linux based on the Debian distribution.

Download and install Raspberry Pi Imager on a Windows computer.

Insert the first SD Card into the SD card reader, select “CHOOSE STORAGE” and write the image to the SD Card, repeat the process for all 3 cards.

When booting up the raspberry you need a login and password

login: pi
password: raspberry

To install the raspberruies you need to have them connected to a network. Easiest is to use cable, just plug it in to your lan but WLAN is possible, however more advanced and not covered here.

At some point you will need to turn of you Raspberries, do not just yank the power coord  out, instead shutdown gracefully by issuing this command

shutdown now
