+# Лабораторная работа №3
+
+## Богданов Дмитрий ПИбд-42
+
+### Для выполнения были выбраны следующие сущности:
+
+* Message - содержит uuid (генерируется), text, datetime_sent, user_id 
+* User - содержит uuid (генерируется), name, surname
+
+Одному пользователю может быть присвоено несколько сообщений.
+
+Соответственно были развернуты 2 сервиса для управления этими сущностями.
+
+### Запуск лабораторной:
+Необходимо перейти в папку с файлом compose.yaml и ввести следующую команду:
+```
+docker-compose up --build -d
+```
+
+## Видео с результатом запуска и тестами...
+
+...можно посмотреть по данной [ссылке](https://drive.google.com/file/d/1cJz0z4KduSz1oltmAuieUW7GxxVLNPNo/view).
