Change url help

This is what is under the about_us.php in controllers

Code:

<?php
class About_us extends Controller {

    function About_us()
    {
        parent::Controller();    
    }
    
    function index()
    {
        $data['section'] = "AboutUs";
        $data['title'] = "About Us";
        $this->load->view('inc/begin', $data);
        $this->load->view('about', $data);
        $this->load->view('inc/end', $data);
    }
}
?>

What should I change?
