- A power supply (either an adapter or a MicroUSB cable);
- An ethernet cable (RJ-45) to connect your Raspberry Pi to your router. (Raspberry Pi Zero users can connect the Pi using an OTG cable, [Wifi dongle](https://core-electronics.com.au/tutorials/raspberry-pi-zerow-headless-wifi-setup.html).);
! We do not recommend the manual installation because it is more technical and longer than using the pre-installed image. This documentation is only intended for advanced users.
! The latest Raspberry Pi OS images requires a screen and a keyboard, as it is no longer possible to connect directly to the Raspberry through SSH. Nevertheless it is possible to re-enable SSH at boot: before starting your Raspberry, put in the boot partition of the SD card an empty file named `ssh` (without extension).
0. Install Raspberry Pi OS Lite on the SD card ([instructions](https://www.raspberrypi.org/downloads/raspberry-pi-os/)). The Raspberry Pi OS Lite can be found here: https://downloads.raspberrypi.org/raspbian_lite/images/
2. Edit `/etc/ssh/sshd_config` to allow SSH login for root, by replacing `PermitRootLogin without-password` with `PermitRootLogin yes`. Reload the SSH daemon with `service ssh reload`.
