 ### A typeface designed for source code
 
-Hack is designed to be a workhorse typeface for source code. It has deep roots in the free, open source typeface community and expands upon the contributions of the [Bitstream Vera](https://www.gnome.org/fonts/) & [DejaVu](http://dejavu-fonts.org/wiki/Main_Page) projects.  The large x-height + wide aperture + low contrast design make it legible at commonly used source code text sizes with a sweet spot that runs in the 8px - 14px range.  The full set of changes to the upstream source are available in the [changelog](CHANGELOG.md).
