Getting started

+

Here’s how to get rolling:

+ +
    +
  1. +

    Create your databases and edit config/database.yml

    +

    Rails needs to know your login and password.

    +
    2. + +
  2. +

    Use script/generate to create your models and controllers

    +

    To see all available options, run it without parameters.

    +
    3. + +
  3. +

    Set up a default route and remove or rename this file

    +

    Routes are setup in config/routes.rb.

    +
