There is nothing new with SassDoc. It has nothing of a revolutionary idea; there are countless of SassDoc projects on GitHub, yet most of them are dead or practically unusable.
Still, we needed this. We needed a way to document our Sass files, APIs, frameworks, libraries and whatever. Thus, this project.
SassDoc is built by Pascal Duez, Valerian Galliat, Hugo Giraudel and Fabrice Weinberg, a.k.a SassDoc team with the help of Why Alix for the design and Reda Lemeden for the logo. And perhaps you, if you feel like contributing!
