 (make sure redis is running)
 
 ## Setup
-Edit `config/db.yml` if you want to point to a different db on your local redis install.
+There is no specific configuration file in use anymore. Everything is configured via command-line options to the noah binary or stored in config.ru.
 
-   * `RACK_ENV` is honored. production listens on 9291, development 9292, test 9293.
-   * `rake sample` populates the development database
-   * `rake spec` populates the test database
+   * The instance of Redis is configured via the `REDIS_URL` env setting. This is honored by Ohm.
+   * Redis DSN strings are in the format of "redis://hostname:port/db"
+   * `RACK_ENV` is honored.
+   * `rake sample["redis://localhost:6379/2"]` populates the locally running redis instance - db 2
+   * `rake spec` runs the test suite (using 'redis://localhost:6379/3' for storing test data)
