+# Tinder Clone
+
+Образовательный проект - клон приложения Tinder, реализованный на Java с использованием Jakarta Servlet API.
+
+## Описание проекта
+
+Это веб-приложение, имитирующее функциональность популярного приложения для знакомств Tinder. Проект разработан в учебных целях для демонстрации навыков разработки на Java EE/Jakarta EE.
+
+## Основной функционал
+
+- **Регистрация и аутентификация пользователей**
+- **Управление профилями** (создание, просмотр, редактирование)
+- **Система ролей** (ADMIN, USER)
+- **Мультиязычность** (поддержка русского и английского языков)
+- **Фильтрация и безопасность** (AuthFilter, ErrorFilter)
+- **Валидация данных**
+
+## Технологический стек
+
+- **Java 17+**
+- **Jakarta Servlet API**
+- **JSP (JavaServer Pages)**
+- **JSTL (Jakarta Standard Tag Library)**
+- **Lombok** (для генерации кода)
+- **SLF4J** (для логирования)
+- **Maven/Gradle** (сборка проекта)
+
+## Архитектура проекта
+
+Проект следует многослойной архитектуре:
+
+```
+src/ru/charm/back/
+├── controller/     # Контроллеры и фильтры
+├── dao/           # Объекты доступа к данным (in-memory storage)
+├── dto/           # Объекты передачи данных
+├── mapper/        # Мапперы между сущностями
+├── model/         # Модели данных и исключения
+├── service/       # Бизнес-логика
+├── utils/         # Утилитные классы
+└── validator/     # Валидаторы
+```
+
+## Основные компоненты
+
+### Модели данных
+- **Profile** - основная сущность пользователя
+- **Gender** - enum (MALE, FEMALE)
+- **Role** - enum (ADMIN, USER)
+- **Status** - enum (ACTIVE, INACTIVE)
+
+### Контроллеры
+- **RegistrationController** - регистрация новых пользователей
+- **LoginController** - аутентификация
+- **ProfileController** - управление профилями
+- **CredentialsController** - управление учетными данными
+- **ContentController** - контент приложения
+- **LanguageController** - переключение языков
+
+### Фильтры
+- **AuthFilter** - фильтр аутентификации
+- **ErrorFilter** - обработка ошибок
+- **HiddenHttpMethodFilter** - поддержка HTTP методов
+- **LanguageFilter** - фильтр языковых настроек
+
+## Установка и запуск
+
+### Требования
+- JDK 17 или выше
+- Apache Tomcat 10+
+- IDE (IntelliJ IDEA рекомендуется)
+
+### Запуск проекта
+1. Клонировать репозиторий
+2. Открыть проект в IDE
+3. Настроить Tomcat Server
+4. Развернуть проект на сервере
+5. Открыть `http://localhost:8080/Tinder_Clone/` в браузере
+
+## Структура данных
+
+Проект использует in-memory хранилище на основе `ConcurrentHashMap` для хранения профилей пользователей. При запуске создаются два тестовых пользователя:
+
+- **Admin**: ivanov@mail.ru / 123
+- **User**: sidorova@mail.ru / 456
+
+## Особенности реализации
+
+- **Singleton паттерн** для DAO и Service слоев
+- **Функциональное программирование** с использованием Stream API
+- **Безопасность** через фильтры и валидацию
+- **Интернационализация** через resource bundles
+- **RESTful подход** в контроллерах
+
+## Возможности для развития
+
+- Интеграция с реальной базой данных (PostgreSQL, MySQL)
+- Добавление WebSocket для real-time функциональности
+- Реализация системы лайков и мэтчей
+- Добавление загрузки фотографий
+- Интеграция с социальными сетями
+- Разработка мобильного приложения
+
+## Автор
+
+Проект разработан в образовательных целях как часть курса по веб-разработке на Java.
+
+## Лицензия
+
+Этот проект предназначен только для образовательных целей.
