Oh, if I had read further into the README I would have seen this: > https://github.com/LycheeOrg/Lychee#build https://github.com/LycheeOrg/Lychee#build > Lychee is ready to use, right out of the box. If you want to contribute and edit CSS or JS files, you need to rebuild https://github.com/LycheeOrg/Lychee-front https://github.com/LycheeOrg/Lychee-front. So their JavaScript source code is in a separate "Lychee-front" repository and they commit the build artifacts into the main "Lychee" repo. Not sure why they would do this.
