Here is one: Unbelievably gorgeous EB Garamond, quite possibly the best open-source typeface:

But there is something more you should add to the readme, here are the instructions to use this on OS X:
Firstly, you can't use this by just installing FontForge from its page, you need command line version of FontForge. That version is much smaller (takes 30 MB or so) and needs to be compiled and installed with Homebrew. I am not going to explain to you how to use Homebrew, there are literally hundreds of guides out there. Just don't use HEAD version,
brew install fonforge is the command you need to install it.
Secondly, you can't use it by internal Python of FontForge, you don't even have an internal Python. But OS X's own Python works perfectly well, just use versions of this command I used with EB Garamond:
Code:
python ./KoboifyFonts-0.3.py -r /Users/msimsek/Downloads/EBGaramond08-Regular.otf -i /Users/msimsek/Downloads/EBGaramond08-Italic.otf -s -k -p -d . 'EB Garamond'
