 Add translation
 ---------------

+   Although the procedure described below still works, it is not recommended for usage any more.
+
+   Since Zammad version 6.3 it's possible to customize any translation via graphical UI. All coupled with handy
+   suggestions for all translatable custom objects in the local system. For more information, see the documentation for the :admin-docs:`translations screen </system/translations.html>`.

 for several languages.
