-Marries the flexible [Kramdown](https://kramdown.rubyforge.org) parser for Markdown with the flexibility of DOM manipulation with [Hexp](https://github.com/plexus/hexp) to generate HTML slides backed by either Reveal.js or Impress.js.
+Create HTML slides from Markdown, backed by Reveal.js, Impress.js, or Deck.js.
 
 Because Slippery slides are the best slides.
 
+When doing conferences you might find yourself on trains, planes, or
+flaky conference wifi. Slippery finds all assets used by your
+presentation and stores them locally, including CSS, Javascript,
+images, and webfonts. You can drop the result on a thumb drive and run
+anywhere, no network required.

 After converting your presentation from Markdown, you can use Hexp to perform transformations on the result. This is what happens with the `processor`, you pass it a CSS selector, each matching element gets passed into the block, and replaced by whatever the block returns. See the [Hexp](http://github.com/plexus/hexp) DSL for details.
