title: Confused about how to install Rails plugins
body: <p>I found an example <a href="http://nubyonrails.com/articles/the-complete-guide-to-rails-plugins-part-i" rel="noreferrer">here</a> showing how to install a Rails plugin. Their example shows this:</p>
  
  <pre><code>./script/plugin install calendar_helper
  </code></pre>
  
  <p>This won't work for me because, confusingly, I don't have anything called <code>plugin</code> in my <code>script</code> directory. All I have is <code>rails</code>:</p>
  
  <pre><code>$ ls script/
  rails
  </code></pre>
  
  <p>So Rails doesn't come with the script you need to install plugins? You need a plugin to install plugins? That doesn't seem very likely. Is something wrong with my Rails project?</p>
