+## Описание
+**Argenta** — Python library for creating TUI
+
+![preview](https://github.com/koloideal/Argenta/blob/kolo/imgs/mock_app_preview_last.png?raw=True)  
+Пример внешнего вида TUI, написанного с помощью Argenta  
+
+---
+
+# Установка
+```bash
+pip install argenta
+```
+or
+```bash
+poetry add argenta
+```
+
+---
+
+# Быстрый старт
+
+Пример простейшей оболочки с командой без зарегистрированных флагов
+```python
+# routers.py
+from argenta.router import Router
+from argenta.command import Command
+
+
+router = Router()
+
+@router.command(Command("hello"))
+def handler():
+  print("Hello, world!")
+```
+
+```python
+# main.py
+from argenta.app import App
+from routers import router
+
+app: App = App()
+
+def main() -> None:
+    app.include_router(router)
+    app.start_polling()
+
+    
+if __name__ == '__main__':
+    main()
+```
+Пример оболочки с командой, у которой зарегистрированы флаги
+
+```python
+# routers.py
+import re
+from argenta.router import Router
+from argenta.command import Command
+from argenta.command.flag import Flags, Flag, InputFlags
+
+router = Router()
+
+registered_flags = Flags(
+    Flag(name='host',
+         prefix='--',
+         possible_values=re.compile(r'^192.168.\d{1,3}.\d{1,3}$')),
+    Flag('port', '--', re.compile(r'^[0-9]{1,4}$')))
+
+
+@router.command(Command("hello"))
+def handler():
+    print("Hello, world!")
+
+
+@router.command(Command(trigger="ssh",
+                        description='connect via ssh',

+def handler_with_flags(flags: InputFlags):
+    for flag in flags:
+        print(f'Flag name: {flag.get_name()}\n'
+              f'Flag value: {flag.get_value()}')
+```

+
+### Примечания  
+
+- В устанавливаемом паттерне сообщения описания команды необходимы быть два ключевых слова: 
+`command` и `description`, каждое из которых должно быть заключено в фигурные скобки, после обработки
+паттерна на места этих ключевых слов будут подставлены соответствующие атрибуты команды, при отсутствии
+этих двух ключевых слов будет вызвано исключение `InvalidDescriptionMessagePatternException`
+
+- Команды оболочки не должны повторяться, при значении атрибута `ignore_command_register` равным `True`
+допускается создание обработчиков для разных регистров одинаковых символов в команде, для примера `u` и `U`,
+при значении атрибута `ignore_command_register` класса `App` равным `False` тот же пример вызывает исключение 
+`RepeatedCommandInDifferentRoutersException`. Исключение вызывается только при наличии пересекающихся команд 
+у __<u>разных</u>__ роутеров
+
+- Наиболее частые сообщение при запуске предопределены и доступны для быстрого
+использования: `argenta.app.defaults.PredeterminedMessages`
+
+<a name="override_defaults"></a>
+- Если `override_system_messages`=`False`, то при переопределении таких атрибутов как `initial_message` и
+`farawell_message` будет использовано дефолтное оформление текста, в виде красного ascii арта, при значении
+`override_system_messages`=`True` системные сообщения будут отображены в точности какими были переданы
+
+
+
+
+### Исключения
+
+- `InvalidRouterInstanceException` — Переданный объект в метод `App().include_router()` не является экземпляром класса `Router`.
+- `InvalidDescriptionMessagePatternException` — Неправильный формат паттерна описания команд.
+- `IncorrectNumberOfHandlerArgsException` — У обработчика нестандартного поведения зарегистрировано неверное количество аргументов(в большинстве случаев у него должен быть один аргумент).
+- `NoRegisteredHandlersException` — У роутера нет ни одного обработчика команд.

+- `history_filename` (`str` | `False`): Путь к файлу, который будет являться или является 
+историй пользовательского ввода, в последующем эти команды будут автодополняться, файл
