Update Localizing Documentation (Drupal configurations)
There is some special mapping configurations for multilingual Drupal sites to map the proper languages between Drupal and CiviCRM. Is there a way I could update the existing documentation?
https://docs.civicrm.org/user/en/latest/the-civicrm-community/localising-civicrm/
`"Inherit CMS language" and regional translations (ex: fr_CA) If you have a multi-lingual site and you are using the "inherit CMS language" configuration option, but wish to, for example, use fr_CA instead of the default fr_FR (for French), you can define a constant in your "civicrm.settings.php" to override the default behavior. See CRM-9558 for more information.
define('CIVICRM_LANGUAGE_MAPPING_FR', 'fr_CA'); `
