+## Установка пакета
+
+Перед тем как начать рассматривать возможности адаптера `psycopg` необходимо установить пакет для Python. 
+
+Как написано в [документации](https://www.psycopg.org/psycopg3/docs/basic/install.html#installation) для начала нужно убедиться, что менеджер пакетов `pip` не ниже версии 20.3:
+
+```bash
+pip install --upgrade pip
+```
+
+Затем установить пакет `psycopg[binary]`, поскольку он не требует установку системных пакетов:
+
+```bash
+pip install "psycopg[binary]"
+```

 ## Основы API библиотеки `psycopg`
 
 Библиотека `psycopg` предоставляет несколько ключевых интерфейсов для работы с PostgreSQL в соответствии со стандартом [**Python DB API 2.0**](https://peps.python.org/pep-0249/).
