<ol>
<li>
<h2>Use <code>rails generate</code> to create your models and controllers</h2>
<p>To see all available options, run it without parameters.</p>
</li>
<li>
<h2>Set up a default route and remove or rename this file</h2>
<p>Routes are set up in config/routes.rb.</p>
</li>
<li>
<h2>Create your database</h2>
<p>Run <code>rake db:migrate</code> to create your database. If you're not using SQLite (the default), edit <code>config/database.yml</code> with your username and password.</p>
