 ## Service Accounts
 
 The settings service needs to know the ID's of service accounts but it doesn't need their secrets. Currently only one service account can be configured which has the admin role. This can be set with the `SETTINGS_SERVICE_ACCOUNT_ID_ADMIN` envvar, but it will also pick up the global `OCIS_SERVICE_ACCOUNT_ID` envvar. Also see the 'auth-service' service description for additional details.
+
+## Default language
+
+The default language can be defined via SETTINGS_DEFAULT_LANGUAGE environment variable. If this variable is not defined, English will be used as default. The value has the ISO 639-1 format ("de", "en", etc.) and is limited by the list supported languages. This setting can be used to set the default language for invitation emails.
