# Register New Shortcodes

To register new shortcodes, developers should use the following code:

```php
public function register_shortcodes() {
    YourNewShortcodes::get_instance();
}

add_action( 'yaymail_register_shortcodes', 'register_shortcodes' );
```

This code attaches to the `yaymail_register_shortcodes` action hook. It is used to register new shortcodes  by passing the shortcodes instance.
