+# Taxonomy of Scala
+This is a repo for my work on the presentation I will be giving at StrangeLoop 2012.  To see the rendered presentation (sans images), go to [this page](https://github.com/jamie-allen/taxonomy-of-scala/blob/master/preso/presentation.md).
+
+A ShowOff presentation based on [Brian Clapper's](https://github.com/scala-phase/scala-orms/tree/master/ScalaQuery) presentation template.
+
+For more information about ShowOff, see [Shawn Chacon's page](https://github.com/schacon/showoff).
+
+## Commands:
+* "rake css" to generate CSS from SASS
+* "rake run" to serve pages (or you can use "showoff serve")
+
+## Requires the following Ruby gems:
+* rubygems
+* showoff
+* sass
+* slidedown
+* albino
+
+## Optional Ruby gems:
+* mongrel (to serve pages with Mongrel instead of WebRick)
+* pdfkit (to generate PDF of presentation)
