Why do I get "Page not found" with my code? I just created a new module but I can't manage to access it.

Here is the home.info.yml

name: Home
description: Ownzones Homepage
type: module
core: 8.x


Here is home.routing.yml

home.oztest:
  path: '/oztest'
  defaults:
    _content: '\Drupal\home\Controller\HomeController::oztest'
    _title: 'Ownzones'
  requirements:
    _permission: 'access content'


And here is the HomeController:

namespace Drupal\home\Controller;

use Drupal\Core\Controller\ControllerBase;

class HomeController extends ControllerBase {
  public function oztest() {
    $element = array(
      '#markup' =&gt; 'Hello, world',
    );

    return $element;
  }
}


I don't see what I'm doing wrong, and when I try to access /oztest I get a message saying The requested page could not be found.
_content is no longer used, wherever you found that is outdated. Use _controller instead.
