-# Telegram-бот для продажи подписок Remnawave
+# Remnawave Minishop
 
-Этот Telegram-бот предназначен для автоматизации продажи и управления подписками для панели **Remnawave**. Он интегрируется с API Remnawave для управления пользователями и подписками, а также использует различные платежные системы для приема платежей.
+![Remnawave Minishop](docs/remnawave-minishop.webp)
 
-## ✨ Ключевые возможности
+Remnawave Minishop - Telegram-бот и Web App (Mini App) для продажи и управления подписками панели [Remnawave](https://docs.rw/). Бот обрабатывает регистрацию, оплату, продление, пробный период, промокоды, рефералов и поддержку в чате. Web App показывает ссылку подключения, срок действия, трафик, оплату, устройства и вход по Telegram Mini Apps `initData`, Telegram OAuth / OpenID Connect и одноразовому email-коду.
 
-### Для пользователей:
--   **Регистрация и выбор языка:** Поддержка русского и английского языков.
--   **Просмотр подписки:** Пользователи могут видеть статус своей подписки, дату окончания и ссылку на конфигурацию.
--   **Мои устройства:** Опциональный раздел для просмотра и отключения подключенных устройств (активируется через переменную `MY_DEVICES_SECTION_ENABLED`).
--   **Пробная подписка:** Система пробных подписок для новых пользователей (активируется вручную по кнопке).
--   **Промокоды:** Возможность применять промокоды для получения скидок или бонусных дней.
--   **Реферальная программа:** Пользователи могут приглашать друзей и получать за это бонусные дни подписки.
--   **Оплата:** Поддержка оплаты через YooKassa, FreeKassa (REST API), CryptoPay, Telegram Stars и Tribute.
+Проект является переработанным форком [kavore/remnawave-tg-shop](https://github.com/kavore/remnawave-tg-shop). Для переноса данных из прежнего стека используйте [инструкцию по миграции](docs/migration-to-minishop.md).
 
-### Для администраторов:
--   **Защищенная админ-панель:** Доступ только для администраторов, указанных в `ADMIN_IDS`.
--   **Статистика:** Просмотр статистики использования бота (общее количество пользователей, забаненные, активные подписки), недавние платежи и статус синхронизации с панелью.
--   **Управление пользователями:** Блокировка/разблокировка пользователей, просмотр списка забаненных и детальной информации о пользователе.
--   **Рассылка:** Отправка сообщений всем пользователям, пользователям с активной или истекшей подпиской.
--   **Управление промокодами:** Создание и просмотр промокодов.
--   **Синхронизация с панелью:** Ручной запуск синхронизации пользователей и подписок с панелью Remnawave.
--   **Логи действий:** Просмотр логов всех действий пользователей.
+## Возможности
 
-## 🚀 Технологии
+Для пользователей:
 
--   **Python 3.11**
--   **Aiogram 3.x:** Асинхронный фреймворк для Telegram ботов.
--   **aiohttp:** Для запуска веб-сервера (вебхуки).
--   **SQLAlchemy 2.x & asyncpg:** Асинхронная работа с базой данных PostgreSQL.
--   **YooKassa, FreeKassa API, aiocryptopay:** Интеграции с платежными системами.
--   **Pydantic:** Для управления настройками из `.env` файла.
--   **Docker & Docker Compose:** Для контейнеризации и развертывания.

-3.  **Запустите контейнеры:**
-    ```bash
-    docker compose up -d
-    ```
-    Эта команда скачает образ и запустит сервис в фоновом режиме.
-
-4.  **Настройка вебхуков (Обязательно):**
-    Вебхуки являются **обязательным** компонентом для работы бота, так как они используются для получения уведомлений от платежных систем (YooKassa, FreeKassa, CryptoPay, Tribute) и панели Remnawave.
-
-    Вам понадобится обратный прокси (например, Nginx) для обработки HTTPS-трафика и перенаправления запросов на контейнер с ботом.
-
-    **Пути для перенаправления:**
-    -   `https://<ваш_домен>/webhook/yookassa` → `http://remnawave-tg-shop:<WEB_SERVER_PORT>/webhook/yookassa`
-    -   `https://<ваш_домен>/webhook/freekassa` → `http://remnawave-tg-shop:<WEB_SERVER_PORT>/webhook/freekassa`
-    -   `https://<ваш_домен>/webhook/cryptopay` → `http://remnawave-tg-shop:<WEB_SERVER_PORT>/webhook/cryptopay`
-    -   `https://<ваш_домен>/webhook/tribute` → `http://remnawave-tg-shop:<WEB_SERVER_PORT>/webhook/tribute`
-    -   `https://<ваш_домен>/webhook/panel` → `http://remnawave-tg-shop:<WEB_SERVER_PORT>/webhook/panel`
-    -   **Для Telegram:** Бот автоматически установит вебхук, если в `.env` указан `WEBHOOK_BASE_URL`. Путь будет `https://<ваш_домен>/<BOT_TOKEN>`.
-
-    Где `remnawave-tg-shop` — это имя сервиса из `docker-compose.yml`, а `<WEB_SERVER_PORT>` — порт, указанный в `.env`.
-
-5.  **Просмотр логов:**
-    ```bash
-    docker compose logs -f remnawave-tg-shop
-    ```
-
-    > 💡 Если включена проверка подписки на канал (`REQUIRED_CHANNEL_ID`), добавьте бота администратором в этот канал. Пользователь увидит кнопку «Проверить подписку», и, после первого успешного подтверждения, дальнейшие действия блокироваться не будут.
-
-## 🐳 Docker
-
-Файлы `Dockerfile` и `docker-compose.yml` уже настроены для сборки и запуска проекта. `docker-compose.yml` использует готовый образ с GitHub Container Registry, но вы можете раскомментировать `build: .` для локальной сборки.
-
-Для автоматической публикации образов настроены GitHub Actions (`.github/workflows`). По умолчанию образы пушатся в GitHub Container Registry и Docker Hub. Добавьте в Secrets репозитория значения `DOCKERHUB_USERNAME` и `DOCKERHUB_TOKEN` (персональный access token или пароль для Docker Hub), чтобы загрузка в Docker Hub работала корректно.

-## 🔮 Планы на будущее
+Минимально заполните в `.env`:
 
--   Расширенные типы промокодов (например, скидки в процентах).
+- `BOT_TOKEN` - токен Telegram-бота;
+- `ADMIN_IDS` - Telegram ID администраторов через запятую;
+- `WEBHOOK_BASE_URL` - публичный URL вебхуков;
+- `POSTGRES_USER`, `POSTGRES_PASSWORD`, `POSTGRES_DB` - доступы PostgreSQL;
+- `WEBAPP_ENABLED=True` - включает Web App и админку для первого входа;
+- `WEBAPP_SESSION_SECRET`, `WEBHOOK_SECRET_TOKEN` - стабильные секреты;
+- `SUBSCRIPTION_MINI_APP_URL` - публичный HTTPS URL Mini App/frontend, например `https://app.domain.com/`;
+- `PANEL_API_URL`, `PANEL_API_KEY`, `PANEL_WEBHOOK_SECRET` - доступ к Remnawave;
+- остальные настройки удобнее задать в Web App админке.
