+# Лабораторная работа №4: Работа с брокером сообщений (RabbitMQ)
+
+## Цель
+
+Изучение проектирования приложений с использованием брокера сообщений RabbitMQ.
+
+---
+
+## Задачи
+
+> 1. **Установить RabbitMQ**  
+     Установите RabbitMQ на локальный компьютер (или используйте Docker).
+>- [Скачивание RabbitMQ](https://www.rabbitmq.com/download.html)
+>- [Релизы RabbitMQ](https://github.com/rabbitmq/rabbitmq-server/releases/)
+>- **Пройти уроки RabbitMQ**
+>- Сделайте скриншоты, показывающие запуск `producer` и `consumer` и передачу сообщений.
