Working!

Hi Dan 

Most of this is just me fixing the documentation, but this is working now on:

On the Heroku machines there's automatically an environment variable called RACK_ENV that is set to production, and that dictates what group is included in the Gemfile. So we use Postgres for production, but yaml for localhost.

You can use this URL, but I'd suggest you follow the instructions and experience the magic of Heroku by deploying to your own server instance. I tested the README, and it totally works.

Awesome that you're starting with Ruby!
