title: a simplification of what a rails project actually is
body: <p>I'm at the point where I can make basic rails apps, and am looking for a better overview of how rails is working.</p>
  
  <p>This is what I am visualising. Is this correct?</p>
  
  <ol>
  <li>Install the rails gem. This also installs a rails script.</li>
  <li><code>rails new ...</code> creates the framework file structure.</li>
  <li>The rails script allows you to interact with your file structure from the command line, but isn't actually doing anything to the rails library itself.</li>
  <li>The "gem 'rails'" in the gem file imports the whole rails library into your new project so in a way, working on a rails app you really just extending the rails gem slightly (relatively speaking) to suit your needs</li>
  </ol>
