User Guide errors

There are a few errors in the user guide on this page

public function view($slug = NULL)
{
       $model = new NewsModel();

       $data['news'] = $model->getNews($slug);

       if (empty($data['news']))
       {
               throw new \CodeIgniter\PageNotFoundException('Cannot page the page: '. $slug);
       }

       $data['title'] = $data['news'][0]['title'];

       echo view('Templates/Header', $data);
       echo view('News/Index', $data);
       echo view('Templates/Footer');
}

<?php
echo '<h2>'.$news['title'].'</h2>';
echo $$news['text'];

page I assume it should be find
[0] shouldn't be there
Index should be View
$ shouldn't be there
