+Что требуется сделать
+
+
+## `Опционально` Список верстаемых страниц
+
+Будут затронуты страницы:
+* page1.html
+* page2.html
+* page3.html
+
+## `Опционально` Список затрагиваемых модулей
+
+При реализации задачи потребуется также реализовать методы контроллера
+
+
+## `Опционально` Список реализуемых функций
+
+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
