+### Using the Python Script
+
+The `pic-to-header` package can also be used directly within a Python script.  Here's an example:
+
+```python
+from pic_to_header.core import process_header_image
+
+# Specify the paths to the input image, mask image, and output image
+input_image_path = "path/to/input_image.png"
+mask_image_path = "path/to/mask_image.png"
+output_image_path = "path/to/output_image.png"
+
+# Generate the header image
+result = process_header_image(input_image_path, mask_image_path, output_image_path)
+
+print(f"Header image generated: {result}")
+```
+
+This script works as follows:
+
+1. Imports the `process_header_image` function from the `pic_to_header.core` module.
+2. Specifies the paths to the input image, mask image, and output image.
+3. Calls the `process_header_image` function to generate the header image.
+4. Displays the path to the generated image.
+
+Running this script will generate the header image at the specified output path.
