Building on this answer:

/** * Implements hook_preprocess_links(). */ function bartik_preprocess_links(&$variables) { if (isset($variables['links']['node-readmore'])) { $variables['links']['node-readmore']['link']['#title'] = t('Read more custom text'); } } 

does anyone know how to build the if statement to further limit the change in the read more link to a particular content type? I'm working in Drupal 8, not 7.
