# ExpressionEngine

> Configure bunny.net CDN with ExpressionEngine to accelerate your website and optimize asset delivery.

Setting up Bunny CDN with ExpressionEngine takes only a single line of configuration plus a template change.

<Steps>
  <Step title="Create a Pull Zone">
    Log in to your [bunny.net dashboard](https://dash.bunny.net) and create a new Pull Zone with your ExpressionEngine site as the origin URL. For details, see [How to create your first Pull Zone](/cdn/quickstart).
  </Step>

  <Step title="Edit your index.php file">
    You'll need SSH or FTP access to your web server. Open the `index.php` file in your site's root and find this line:

    ```php theme={null}
    // $assign_to_config['global_vars'] = array();
    ```

    Uncomment it and define a global variable for your CDN URL, replacing the hostname with your Pull Zone:

    ```php theme={null}
    $assign_to_config['global_vars'] = array('cdn_url' => 'https://YOURZONE.b-cdn.net/');
    ```
  </Step>

  <Step title="Use the variable in your templates">
    Update your templates to reference the new `{cdn_url}` variable when linking to static resources. For example:

    ```text theme={null}
    {cdn_url}uploads/image.jpg
    ```
  </Step>

  <Step title="Test the integration">
    Load your site and confirm that the URLs for your static content now include your Pull Zone hostname. Once they do, ExpressionEngine is serving assets through Bunny CDN.
