+# Run status-board on a Raspberry Pi
+
+This folder contains scripts to configure a Pi to run the status board.
+You can install a [Raspberry Pi OS Lite](https://www.raspberrypi.com/software/operating-systems/)
+and use the [bootstrap.sh](bootstrap.sh) script to set it up:
+
+```shell
+# Install Raspberry Pi OS Lite (32bit) (https://www.raspberrypi.com/software/operating-systems/)
+# Setup username, password, hostname, ssh and autologin (without desktop) with
+sudo raspi-config
+# Download and extract latest bootstrap archive
+wget -qO- https://github.com/RoboCup-SSL/ssl-status-board/releases/latest/download/bootstrap.tar.gz | tar xvz
+# Run bootstrap script
+./rpi/bootstrap.sh
+```
