+### Лабораторная работа №4 - Работа с брокером сообщений
+
+#### Задание
+
+1. Установить брокер сообщений RabbitMQ.
+2. Пройти уроки 1, 2 и 3 из RabbitMQ Tutorials на любом языке программирования.
+3. Продемонстрировать работу брокера сообщений.
+
+#### Описание работы программы:
+
+- **Класс Publisher** успешно осуществляет отправку сообщений своим клиентам.
+  
+- **Класс Consumer1** принимает и обрабатывает сообщения с задержкой в 3 секунды, что можно заметить на видео.
+
+- **Класс Consumer2** мгновенно принимает и обрабатывает сообщения.
+
+## Видео
