The Raspberry Pi Imager is a great piece of software for preparing your SD cards for use with Raspberry Pis. However, if you’re setting up a number of Raspberry Pis you will find that you still need to connect a monitor, keyboard and mouse to them to complete the setup, to:
- update the wifi ssid and password
- change the hostname and default password
- change localization settings
There is another, better alternative to doing those 3 steps - use the Raspberry Pi Imager secret menu.
