How to Use Vanna AI

To get started with Vanna AI, follow these steps:

1. Install Vanna AI: Use pip to install the Vanna package:

   pip install vanna

2. Train the Model: Provide training data, such as Data Definition Language (DDL) statements, SQL queries, and documentation, to train the model:

       vn.train(ddl="CREATE TABLE ...")
       vn.train(sql="SELECT ...")
       vn.train(documentation="...")

3. Ask Questions: After training, you can ask questions in natural language:

   vn.ask("What are the top 10 customers by sales?")

4. Integrate with Frontend: Develop a user interface using frameworks like Streamlit or Flask to interact with the model.
