 Quickpreso is an attempt to make prototyping presentations be more like prototyping HTML pages.
 
-Whether this is a good idea remains to be seen.

+
+## Requirements ##
+
+To generate presentations, you need:
+
+* OS X 10.6 or higher
+* [ffmpeg][]
+
+The generated presentations use [Popcorn.js][] for syncing audio to video content. Currently, the audio is only produced in Ogg Vorbis format, so only Firefox and Chrome can be used to view presentations.
+
+  [ffmpeg]: http://ffmpeg.org/
+  [Popcorn.js]: http://popcornjs.org/
+
+## Quick Start ##
+
+1. Edit the [script.html][] to your liking. Each plain-text line is text to be narrated, while all HTML elements are slides that the narration voices over.
+
+2. Run `python quickpreso.py`. This will use OS X's `say` command-line tool to automatically generate audio for your narration and `ffmpeg` to convert the final audio to Ogg Vorbis. It also generates information about where slide changes occur in the narration.
+
+3. View [index.html][] in Firefox or Chrome.
+
+4. Repeat steps 1-3 as necessary until you're happy with your presentation. When you're finished, just upload everything in the `static-files` directory to a web server.
