Keynote templates are available for download to the members of the GitHub organization on Google Drive.

A new presentation can be created by opening github-presentation-template-v2020.key or github-presentation-theme-v2020.kth.
To install, open the theme file (.kth) in Keynote and click Add to Theme Chooser.

You will now have the theme available any time you open Keynote.
