+# Erlang ODBC Series Example
+
+Минимальный Erlang-клиент для YDB ODBC. Повторяет основной сценарий C++ `basic_example`: создает таблицы `series`, `seasons`, `episodes`, заполняет их тестовыми данными, выполняет несколько запросов и удаляет таблицы.
+
+## Требования
+
+- Erlang/OTP с модулем `odbc`
+- unixODBC
+- Собранный и зарегистрированный YDB ODBC driver
+- Запущенная YDB, доступная по строке подключения
+
+Проверить регистрацию драйвера:
+
+```bash
+odbcinst -q -d
+```
+
+## Запуск
+
+По умолчанию используется `Driver=YDB;Endpoint=localhost:2136;Database=/local;`.
+
+```bash
+make run
+```
+
+С другой строкой подключения:
+
+```bash
+make run CONN='...'
+```
