    # AB InBev Data Science Challenge
    Welcome to the AB InBev Data Science Challenge demo! This interactive tool is designed to help you forecast the **SOM** and **Volume** series, and analyze their price sensitivity.
    ## How to use this demo?
    Using this demo is simple and straightforward. Just follow these steps:
    1. Select the series you want to forecast from the dropdown menu. The valid options are **SOM** and **Volume**.
    2. Specify the number of months ahead for your forecast.
    3. Choose the desired price variation compared to the previous year. A value of 0 indicates that the future price values will be the same as the previous year.
    
    That's it! You're ready to explore and analyze the forecasted series. Enjoy!
