    ## Instructions
    1. Enter your Together API Key (get one from https://www.together.ai)
    2. Enter a descriptive prompt in the text box
    3. Adjust the width, height, and steps as needed
        - Width and height control the dimensions of the generated image
        - Steps control the number of diffusion steps (higher = more detail but slower)
    4. Click "Generate Image" 
    5. Wait for the image to be generated
    
    Note: Your API key is not stored and is only used for the current session.
