-    <em>Telegram Bots Rapid Application Development (RAD) Framework.</em>
-</p>
-
-**QBot** is a library for fast development of Telegram bots and mini-apps following the **RAD (Rapid Application Development)** principle in a **declarative style**.
-
-## Key Features
-
-- **Automatic CRUD Interface Generation** – Manage objects effortlessly without manual UI coding.
-- **Built-in Field Editors** – Includes text inputs, date/time pickers, boolean switches, enums, and entity selectors.
-- **Advanced Pagination & Filtering** – Easily organize and navigate large datasets.
-- **Authentication & Authorization** – Role-based access control for secure interactions.
-- **Context Preservation** – Store navigation stacks and user interaction states in the database.
-- **Internationalization Support** – Localizable UI and string fields for multilingual bots.
-
-**QBot** powered by **[FastAPI](https://fastapi.tiangolo.com)**, **[SQLModel](https://sqlmodel.tiangolo.com)** & **[aiogram](https://aiogram.dev)** – Leverage the full capabilities of these frameworks for high performance and flexibility.
-
-## Benefits
-
-- **Faster Development** – Automate repetitive tasks and build bots in record time.
-- **Highly Modular** – Easily extend and customize functionality.
-- **Less Code Duplication** – Focus on core features while QBot handles the rest.
-- **Enterprise-Grade Structure** – Scalable, maintainable, and optimized for real-world usage.
-
-## Example
-```python
-class AppEntity(BotEntity):
-    """
-    BotEntity - business entity. Based on SQLModel, which provides ORM functionality,
-    basic CRUD functions and additional metadata, describing entities view and behaviour
-    """

-    <em>Telegram Bots Rapid Application Development (RAD) Framework.</em>
-</p>
-
-**QBot** is a library for fast development of Telegram bots and mini-apps following the **RAD (Rapid Application Development)** principle in a **declarative style**.
-
-## Key Features
-
-- **Automatic CRUD Interface Generation** – Manage objects effortlessly without manual UI coding.
-- **Built-in Field Editors** – Includes text inputs, date/time pickers, boolean switches, enums, and entity selectors.
-- **Advanced Pagination & Filtering** – Easily organize and navigate large datasets.
-- **Authentication & Authorization** – Role-based access control for secure interactions.
-- **Context Preservation** – Store navigation stacks and user interaction states in the database.
-- **Internationalization Support** – Localizable UI and string fields for multilingual bots.
-
-**QBot** powered by **[FastAPI](https://fastapi.tiangolo.com)**, **[SQLModel](https://sqlmodel.tiangolo.com)** & **[aiogram](https://aiogram.dev)** – Leverage the full capabilities of these frameworks for high performance and flexibility.
-
-## Benefits
-
-- **Faster Development** – Automate repetitive tasks and build bots in record time.
-- **Highly Modular** – Easily extend and customize functionality.
-- **Less Code Duplication** – Focus on core features while QBot handles the rest.
-- **Enterprise-Grade Structure** – Scalable, maintainable, and optimized for real-world usage.

-## Example
-```python

-    basic CRUD functions and additional metadata, describing entities view and behaviour
