It's there now (thanks for the alert!), but I don't think the main branch was there when I wrote the parent comment. If I recall correctly, it was just the gh-pages branch like these other repos from OP: https://github.com/txstc55/Ducked-support and https://github.com/txstc55/duck-duck-duck.

(Of course, those repos may have main pushed later as well, invalidating this comment too)

Nice of the author to share the code. Thanks!
