+# Go Chat Bridge
+
+Мультичат-бот для объединения Telegram и Discord.
+
+## Возможности
+- Пересылка сообщений между Telegram и Discord
+- Отображение имени отправителя в пересылаемых сообщениях
+- Поддержка медиафайлов (изображения, видео, документы)
+
+## Быстрый старт
+
+1. Клонируйте репозиторий:
+   ```bash
+   git clone <repo_url>
+   cd turn-rox-bridge
+   ```
+2. Установите зависимости:
+   ```bash
+   go mod tidy
+   ```
+3. Создайте и настройте ботов/токены для платформ:
+   - Telegram: получите токен у @BotFather
+   - Discord: создайте приложение и получите токен
+4. Укажите переменные окружения:
+   ```bash
+   export TELEGRAM_TOKEN=...         # токен Telegram-бота
+   export DISCORD_TOKEN=...          # токен Discord-бота
+   export TELEGRAM_CHAT_ID=...       # id чата/канала Telegram
+   export DISCORD_CHANNEL_ID=...     # id канала Discord
+   export DISCORD_REACTION_CHANNEL_ID=...  # доп. канал Discord для дубля по реакции
+   export TELEGRAM_DUPLICATE_REACTION=✍️   # какая реакция триггерит дубль
+   ```
+5. Запустите приложение:
+   ```bash
+   go run .
+   ```
+
+## Формат пересылаемых сообщений
+
+- `[TG] user: текст` — из Telegram
+- `[DS] user: текст` — из Discord
+
+## Пример .env
+
+Создайте файл `.env` в корне проекта и заполните:
+
+```env
+TELEGRAM_TOKEN=your_telegram_token
+DISCORD_TOKEN=your_discord_token
+TELEGRAM_CHAT_ID=-1001234567890
+DISCORD_CHANNEL_ID=123456789012345678
+DISCORD_REACTION_CHANNEL_ID=123456789012345679
+TELEGRAM_DUPLICATE_REACTION=✍️
+```
+
+docker-compose автоматически подхватит эти переменные.
+
+## Дублирование по реакции Telegram
+
+Если у Telegram-сообщения добавлена реакция, указанная в `TELEGRAM_DUPLICATE_REACTION` (по умолчанию `✍️`), то это сообщение дополнительно отправляется в `DISCORD_REACTION_CHANNEL_ID` помимо основного `DISCORD_CHANNEL_ID`.
+## TODO
+- Поддержка вложений и файлов
+- Админ-команды
+- Логирование событий
