title: How to deploy Rails in production mode?
body: <p>How do I put a Rails 3.0 in production mode?</p>
  
  <p>Do I simply just put the following code in config/environment:</p>
  
  <pre><code>RAILS_ENV = 'production'
  </code></pre>
  
  <p>Is there anything else I need to change?</p>
  
  <p>Thank you.</p>
