title: Codeignite hello world code in docs doent work
body: <p>I just started using CodeIgniter and I'm stuck at the hello world code in the docs. Each time I type in the name of the blog controller in the url bar and hit enter, I get this error:
  <a href="https://i.stack.imgur.com/4yBKB.jpg" rel="nofollow noreferrer">404 Error Page Not Found!</a>

              public function index()
              {
                      echo 'Hello World!';
              }
      }
  </code></pre>
