+
+## Требования
+
+- PHP 8.2+
+- PostgreSQL 14+
+- Apache с mod_rewrite или Nginx
+- Docker (опционально)
+
+## Установка
+
+### Вариант 1: Docker (рекомендуется)
+
+```bash
+# Клонировать репозиторий
+git clone <repository-url>
+cd aeterna
+
+# Запустить контейнеры
+docker-compose up -d
+
+# Приложение будет доступно по адресу:
+# http://localhost:8080
+```
+
+### Вариант 2: Локальный сервер
+
+#### Apache
+
+1. Настройте DocumentRoot на директорию `public/`
+
+```apache
+<VirtualHost *:80>
+    ServerName aeterna.local
+    DocumentRoot /path/to/aeterna/public
+    
+    <Directory /path/to/aeterna/public>
+        Options -Indexes +FollowSymLinks
+        AllowOverride All
+        Require all granted
+    </Directory>
+</VirtualHost>
+```
+
+2. Включите mod_rewrite:
+```bash
+sudo a2enmod rewrite
+sudo systemctl restart apache2
+```
+
+#### Nginx
+
+```nginx
+server {
+    listen 80;
+    server_name aeterna.local;
+    root /path/to/aeterna/public;
+    index index.php;
+
+    location / {
+        try_files $uri $uri/ /index.php?$query_string;
+    }
+
+    location ~ \.php$ {
+        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
+        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
+        include fastcgi_params;
+    }
+
+    location ~ /\.(?!well-known).* {
+        deny all;
+    }
+}
+```
+
+## Конфигурация
+
+### База данных
+
+Отредактируйте `config/database.php` или используйте переменные окружения:
+
+```bash
+export DB_HOST=localhost
+export DB_PORT=5432
+export DB_DATABASE=aeterna
+export DB_USERNAME=user
+export DB_PASSWORD=password
+```
+
+### Приложение
+
+Отредактируйте `config/app.php`:
+
+- `debug` - режим отладки (false для продакшена)
+- `url` - URL приложения
+- `admin_emails` - email адреса администраторов
+
+## Функционал
+
+### Для покупателей
+- Каталог товаров с фильтрацией
+- Корзина покупок
+- Оформление заказов
+- Регистрация и авторизация
+
+### Для администраторов
+- Управление товарами
+- Управление категориями
+- Управление заказами
+- Управление пользователями
+
+## Маршруты
+
+| Метод | URL | Описание |
+|-------|-----|----------|
+| GET | `/` | Главная страница |
+| GET | `/catalog` | Каталог товаров |
+| GET | `/product/{id}` | Страница товара |
+| GET | `/cart` | Корзина |
+| GET | `/login` | Вход |
+| GET | `/register` | Регистрация |
+| GET | `/admin` | Админ-панель |
+
+## Технологии
+
+- **Backend**: PHP 8.2, MVC архитектура
+- **Database**: PostgreSQL
+- **Frontend**: HTML5, CSS3/LESS, JavaScript, jQuery
+- **Сервер**: Apache/Nginx
+- **Контейнеризация**: Docker

+# Миграции базы данных
+
+## Применение миграции для системы отзывов
+
+Эта миграция добавляет полноценную систему отзывов с рейтингом (1-5 звезд) для товаров.
+
+### Что добавляется:
+
+1. **Новая таблица `reviews`** с полями:
+   - `review_id` - уникальный идентификатор отзыва
+   - `product_id` - связь с товаром
+   - `user_id` - связь с пользователем
+   - `rating` - оценка от 1 до 5
+   - `comment` - текст отзыва
+   - `is_approved` - статус модерации
+   - `created_at`, `updated_at` - временные метки
+
+2. **Обновление таблицы `products`**:
+   - `rating` - средний рейтинг товара (автоматически рассчитывается)
+   - `review_count` - количество отзывов (автоматически обновляется)
+
+3. **Триггеры и функции PostgreSQL**:
+   - Автоматическое обновление рейтинга товара при добавлении/изменении/удалении отзыва
+   - Автоматическое обновление `updated_at` при изменении отзыва
+
+### Инструкция по применению:
+
+#### Способ 1: Через командную строку PostgreSQL
+
+```bash
+# Подключитесь к базе данных
+psql -h 185.130.224.177 -p 5481 -U admin -d postgres
+
+# Выполните миграцию
+\i /path/to/cite_practica1/database/migrations/add_reviews_system.sql
+
+# Проверьте, что таблица создана
+\dt reviews
+
+# Проверьте структуру таблицы
+\d reviews
+
+# Проверьте новые поля в таблице products
+\d products
+```
+
+#### Способ 2: Через DBeaver или другой GUI-клиент
+
+1. Откройте файл `add_reviews_system.sql`
+2. Скопируйте весь SQL-код
+3. Вставьте в окно SQL-редактора вашего клиента
+4. Выполните скрипт
+
+#### Способ 3: Через PHP скрипт (если есть доступ к серверу)
+
+Создайте временный файл `apply_migration.php`:
+
+```php
+<?php
+require_once __DIR__ . '/../../app/Core/Database.php';
+
+use App\Core\Database;
+
+$sql = file_get_contents(__DIR__ . '/add_reviews_system.sql');
+
+try {
+    $db = Database::getInstance();
+    $db->getConnection()->exec($sql);
+    echo "✓ Миграция успешно применена!\n";
+} catch (Exception $e) {
+    echo "✗ Ошибка: " . $e->getMessage() . "\n";
+}
+```
+
+Затем выполните:
+```bash
+php apply_migration.php
+```
+
+### Проверка установки:
+
+После применения миграции выполните следующие SQL-запросы для проверки:
+
+```sql
+-- Проверка таблицы reviews
+SELECT * FROM reviews LIMIT 1;
+
+-- Проверка новых полей в products
+SELECT product_id, name, rating, review_count FROM products LIMIT 5;
+
+-- Проверка триггеров
+SELECT tgname FROM pg_trigger WHERE tgrelid = 'reviews'::regclass;
+
+-- Проверка функций
+SELECT proname FROM pg_proc WHERE proname LIKE '%review%' OR proname LIKE '%rating%';
+```
+
+### Тестирование системы отзывов:
+
+1. **Откройте страницу любого товара** в каталоге
+2. **Убедитесь, что видна секция "Отзывы о товаре"** с формой для добавления отзыва
+3. **Оставьте тестовый отзыв**:
+   - Выберите рейтинг (1-5 звезд)
+   - Напишите комментарий
+   - Нажмите "Отправить отзыв"
+4. **Проверьте, что**:
+   - Отзыв появился в списке
+   - Рейтинг товара обновился
+   - Количество отзывов увеличилось
+
+### API endpoints для отзывов:
+
+- `POST /reviews` - создание отзыва
+- `POST /reviews/{id}` - обновление отзыва
+- `POST /reviews/{id}/delete` - удаление отзыва
+- `GET /reviews/product/{id}` - получение отзывов товара (AJAX)
+- `POST /reviews/{id}/toggle-approval` - модерация отзыва (только для админов)
+
+### Права доступа:
+
+- **Обычные пользователи**: могут оставлять, редактировать и удалять свои отзывы
+- **Администраторы**: 
+  - НЕ могут оставлять отзывы
+  - Могут удалять любые отзывы
+  - Могут модерировать отзывы (одобрять/отклонять)
+
+### Ограничения:
+
+- Один пользователь может оставить только один отзыв на товар
+- Рейтинг обязателен (от 1 до 5)
+- Комментарий опционален, максимум 1000 символов
+- Администраторы не могут оставлять отзывы
+
+### Откат миграции (если нужно):
+
+```sql
+-- ВНИМАНИЕ: это удалит все отзывы!
+DROP TRIGGER IF EXISTS trigger_review_delete_update_product_rating ON reviews;
+DROP TRIGGER IF EXISTS trigger_review_insert_update_product_rating ON reviews;
+DROP TRIGGER IF EXISTS trigger_reviews_updated_at ON reviews;
+DROP FUNCTION IF EXISTS trigger_update_product_rating();
+DROP FUNCTION IF EXISTS update_product_rating(INTEGER);
+DROP FUNCTION IF EXISTS update_reviews_updated_at();
+DROP TABLE IF EXISTS reviews CASCADE;
+
+-- Удаление полей из products (опционально)
+ALTER TABLE products DROP COLUMN IF EXISTS rating;
+ALTER TABLE products DROP COLUMN IF EXISTS review_count;
+```
+
+### Поддержка:
+
+Если возникли проблемы с миграцией:
+1. Проверьте права доступа к базе данных
+2. Убедитесь, что используется PostgreSQL 10+
+3. Проверьте логи ошибок PostgreSQL
+4. Убедитесь, что таблицы `users` и `products` существуют
