-После выполнения задачи станет доступным:
-* просмотр `entity_name`
-* редактирование `entity_name`
-* валидация `entity_name`
-
-## `Опционально` Сценарии работы
-
-Сценарий просмотра:
-1. Зайти на главную страницу приложения
-2. Перейти в раздел `section_name`
-3. Перейти к списку `entity_name`
-4. Выбрать нужную `entity_name` и нажать на нее
