title: How to generate docs for my models and controller in rails
body: <p>I want to create docs for the models and controller of my application. Even for rake task, any background job. As I have thousands of lines of comments inline between the code, explanation of the all the functions actions..</p>
  
  <p>I don't want docs for rails so </p>
  
  <pre><code>  rake doc:rails 
  </code></pre>
  
  <p>is useless for me.</p>
  
  <p>Usecase is internal detailed developer notes.</p>
