 ## How can I alter the generated links?
 
-You may implement `hook_language_switch_links_alter()` provided by Drupal Core in a custom module or use any other contributed module that implements that hook to alter the language switcher links. Alternatively, you may override `menu.html.twig` in your custom theme (see below) or implement a preprocess function.

 ## How do I target the links in Twig templates?
 
-You can check, if the id of the menu link starts with `language_switcher_menu.language_switcher_link:`. `item.original_link.class` or `item.original_link.provider` are also a good candidates to check, whether the links have been generated by Language Switcher Menu module. If needed, you can get the language object using `item.original_link.getOptions()['language']`. Below is an example of a custom `menu.html.twig` template that uses custom markup for language switcher links:
