 One option is to download the disk image file and write it to a 16GB micro SD card or larger.  The image is based on Raspberry Pi OS (Rasbian) Lite, dated December 2020. All software is installed, you just need to login to change your password and set your amateur radio callsign if you have one.  You can run the ./update.sh script to update all packages and update and compile the latest CubeSatSim software.
 
-The other option is to start with a Buster Raspberry Pi OS (Rasbian) image and run the installation script ./install.sh which will install and compile all the related software. Note that the installation script does not yet work with Bullseye.  This includes the following packages:

-CubeSatSim runs on the Buster version of Raspberry Pi OS (Desktop or Lite), although a Pi Zero or Pi Zero W should only run Lite.  Your Pi will need to have internet access to update settings and install packages.  The software does NOT yet support Bullseye due to changes in the Pi Camera (thanks Raspberry Pi for the lack of backwards compatibility!!)
