+Contributing
+------------

+The master file is `src/Cantarell.glyphs`. To contribute, you need to:
+
+-      Use the proprietary and Mac-only Glyphs.app...
+-      ...or generate UFOs from it by using `fontmake -g src/Cantarell.glyphs -o ufo`. You can then open the 
masters in `master_ufo` with any design app that supports it. Send the contribution to Nikolaus Waxweiler

Glyphs files and UFOs, at which point I'll switch over and you'll be able to use any UFO editor you'd like. 
Rejoice!
