 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).

 The [alt-hack](https://github.com/source-foundry/alt-hack) library includes a (growing) collection of alternate glyph styles that can be used to customize your Hack fonts.  Don't like the default zero style?  Swap out the UFO design source with a slashed zero or dotted zero and build new fonts that work better for you.
 
-Contributions of new glyph styles are welcomed in the alt-hack repository.  Design something new that works well with rest of the typeface and submit a pull request to the alt-hack repository so that others can use it in their own custom builds.
