-"# monster_monitor_v2" 
+# Monster Monitor v2
+
+Windows-приложение (WinForms, .NET Framework 4.7.2) для мониторинга процесса `ss.exe`, поддержки SSH-туннеля и контроля состояния сервисов с логированием в UI.
+
+## Возможности
+
+- мониторинг и автоподдержка процесса `ss.exe`;
+- управление SSH-туннелем;
+- предотвращение засыпания системы во время работы;
+- логирование событий в консоль приложения;
+- хранение настроек в локальном профиле пользователя;
+- автообновление через GitHub Releases (с проверкой раз в час);
+- поддержка proxy для запросов к GitHub API и скачивания релизов.
+
+## Требования
+
+- Windows 10+;
+- .NET Framework 4.7.2 (target `net472`);
+- доступ к GitHub (напрямую или через proxy).
+
+## Сборка и запуск
+
+Из корня репозитория:
+
+```powershell
+dotnet build .\src\MonsterMonitor\MonsterMonitor.csproj
+dotnet run --project .\src\MonsterMonitor\MonsterMonitor.csproj
+```
+
+Или откройте `src/MonsterMonitor.sln` в Visual Studio и запустите проект `MonsterMonitor`.
+
+## Настройки
+
+Настройки сохраняются в:
+
+`%LOCALAPPDATA%\MonsterMonitor\settings.ini`
+
+Основные параметры:
+
+- `SshHost`, `SshPort`, `SshUsername`, `SshPasswordProtected`;
+- `RemotePort`, `LocalPort`;
+- `MaxPingFailures`, `ReconnectTimeoutSec`;
+- `SsProcessPath`, `SsArguments`;
+- `Proxy` — адрес proxy для GitHub-запросов (пример: `http://host:port`).
+
+Часть паролей хранится в защищенном виде через DPAPI.
+
+## Автообновление
+
+Приложение проверяет новые версии в GitHub репозитории:
+
+- owner: `monster1025`
+- repo: `monster_monitor_v2`
+
+Логика:
+
+1. Определяется текущая версия приложения.
+2. Получается последняя версия релиза из GitHub.
+3. Если версия новее текущей — скачивается `.zip`-ассет релиза.
+4. Обновление подготавливается в директории приложения:
+   - `.\update\<version>\update.zip`
+   - `.\update\<version>\extracted`
+   - `.\update\<version>\apply_update.bat`
+5. Пользователю предлагается перезапустить приложение для применения обновления.
+
+Периодичность проверки: каждые 60 минут (и первичная проверка после старта приложения).
+
+## Интерфейс
+
+- Главное окно:
+  - кнопка `Настройки`;
+  - кнопка `Выход`;
+  - консоль логов (уровни: Debug/Info/Warn/Error).
+- При сворачивании окно уходит в трей.
+
+## Примечания
+
+- Для автообновления релиз должен содержать `.zip`-ассет с файлами приложения.
+- Если `/releases/latest` недоступен, используется fallback на список релизов `/releases`.
