 Usage
 ====================
 
-To try ShowOff, clone this repo and run ./bin/showoff, which will start
-up the Sinatra server and serve the examples/ directory. Eventually this
-will be gemified and you can run it in any ShowOff directory.
+ShowOff is meant to be run in a ShowOff formatted repository - that means that it has
+a showoff.json file and a number of sections (subdirectories) with markdown files for
+the slides you're presenting.
+
+  $ gem install showoff
+  $ git clone (showoff-repo)
+  $ cd (showoff-repo)
+  $ showoff
+
+If you run 'showoff' in the ShowOff directory itself, it will show an example presentation
+from the 'example' subdirectory, so you can see what it's like.
 
 Real World Usage

-So far, showoff has been used in the following presentations:

 Future Plans
 ====================
 
-Right now it comes with an example presentation (my LinuxConf.au talk)
-that will probably change or go away at some point.  I would like this
-to eventually be a general tool rather than having the presentation in
-the showoff repo.  Eventually.  So you would install showoff as a gem
-and then have just the presentation as your git repo (or whatever) and
-run 'showoff' in the repo to start the presentation.

 I really want this to evolve into a dynamic presentation software server,
 that gives the audience a lot of interaction into the presentation - 
 helping them decide dynamically what the content of the presentation is,
