+# Films API
+
+Це проєкт, що реалізує REST API для отримання та передачі інформації про фільми. АПІ надає можливість отримувати дані про фільми, акторський склад, рейтинги, відгуки користувачів, опис фільму та цікаві факти про них.
+
+## Діаграма класів
+
+
+
+Film: Представляє фільм із всією відповідною інформацією, такою як назва, рейтинг, актори тощо.
+
+FilmService: Надає функціональність для операцій над фільмами, таких як додавання, редагування та видалення.
+
+FilmController: Обробляє HTTP-запити із використанням Spring Boot та взаємодіє з FilmService.
+
+FilmWriter: Забезпечує збереження та вичитку даних у форматі CSV.
+Залежності проєкту
+
+### Проект побудований з використанням наступних технологій та бібліотек:
+
+**Java 17**
+
+**Spring Boot**
+
+**Lombok**
+
+**Maven**
+
+## Інструкції запуску
+
+Щоб запустити цей проект, виконайте наступні кроки:
+
+Клонуйте репозиторій проекту:
+`git clone https://github.com/ledan404/coursework.git`
+
+Перейдіть до каталогу проекту:
+`cd coursework`
+Запустіть проект за допомогою Maven:
+`mvn spring-boot:run`
+Проект буде запущено на http://localhost:8080.
+
+## REST запити
+
+Проект надає наступні REST API для отримання та передачі даних про фільми:
+
+GET /films: Повертає всі фільми, що присутні в системі.
+
+GET /films/{id}: Повертає фільм із вказаним ідентифікатором.
+
+POST /films: Додає новий фільм.
+
+PUT /films/{id}: Оновлює фільм із вказаним ідентифікатором.
+
+DELETE /films/{id}: Видаляє фільм із вказаним ідентифікатором.
+
+## Тестування
+
+ У проекті використовуються юніт-тести для перевірки логіки запису та пошуку файлів на файловій системі. Щоб запустити тести, виконайте наступну команду:
+
+`mvn test`
+
+## Перевірка якості коду
+
+Код проекту можна перевірити за допомогою інструментів Spotbugs та Checkstyle. Щоб запустити перевірку, виконайте наступні команди:
+
+`mvn spotbugs:check`
+
+`mvn checkstyle:check`
