-# Attentive
+Attentive is a new take on Ruby presentation software. It provides lots of smart things already set up for you:
 
-TODO: Write a gem description
+* A simple slide transition system using a slightly hacked up version of Fathom.js.
+* Sass, Compass, and CoffeeScript all plugged into Sprockets and ready to generate your presentation's CSS and JavaScripts.
