+# Chatbot Database Structure
+
+This project implements a chatbot that can interact with users and provide information about the structure of a database. The chatbot is designed to be easy to use and requires minimal coding knowledge to operate.
+
+## Project Structure
+
+```
+chatbot-db-structure
+├── src
+│   ├── main.py               # Entry point of the application
+│   ├── chatbot.py            # Contains the Chatbot class for managing conversations
+│   ├── db
+│   │   ├── __init__.py       # Initializes the db package
+│   │   ├── connector.py       # Handles database connection
+│   │   └── schema.py         # Retrieves and formats the database schema
+│   └── utils
+│       └── helpers.py        # Utility functions for various tasks
+├── requirements.txt          # Lists project dependencies
+├── .env.example              # Example environment variables
+└── README.md                 # Documentation for the project
+```
+
+## Setup Instructions
+
+1. Clone the repository:
+   ```
+   git clone <repository-url>
+   cd chatbot-db-structure
+   ```
+
+2. Create a virtual environment:
+   ```
+   python -m venv venv
+   ```
+
+3. Activate the virtual environment:
+   - On Windows:
+     ```
+     venv\Scripts\activate
+     ```
+   - On macOS/Linux:
+     ```
+     source venv/bin/activate
+     ```
+
+4. Install the required dependencies:
+   ```
+   pip install -r requirements.txt
+   ```
+
+5. Configure your environment variables by copying `.env.example` to `.env` and filling in the necessary values.
+
+## Usage
+
+To start the chatbot, run the following command:
+```
+python src/main.py
+```
+
+Once the chatbot is running, you can ask questions about the database structure, and it will respond with relevant information.
+
+## Capabilities
+
+- Provides information about the database schema, including tables and their columns.
+- Allows users to interact naturally and receive structured responses.
+- Designed to be extensible for future enhancements and additional features.
+
+## Contributing
+
+Contributions are welcome! Please feel free to submit a pull request or open an issue for any suggestions or improvements.
