This is an update to an older post about how to Turn a Raspberry Pi into an Astrophotography Autoguider. I rebuilt my autoguider from scratch with newer versions of the software. It's even a bit easier now.

Step 1: Install Raspberry Pi OS

Follow the official instructions and install the "Raspberry Pi OS with desktop and recommended software". All of the commands in the steps that follow are run from a terminal session on the Raspberry Pi.

Step 2: Install Git

UPDATE (2021-03-31): I've posted an improved version of this guide with newer versions of the software.
