Модул:Multiple image
 |
Ин модул ҳуҷҷатгузории кофӣ надорад.
Вы можете помочь проекту, создав описание модуля: что он делает, как его использовать, какие параметры он принимает, в какие категории добавляет. Это поможет другим использовать его. P.S. Также не забываем про категорию и интервики. P.P.S. Некоторые советы по оформлению есть на странице проекта «Документирование шаблонов». |
