+## new_python_based_image.py
+
+This Python script generates a new folder structure for a Python-based project by copying an existing one and updating Python version references. It performs the following steps:
+
+1. Copy Folder: Duplicates the specified folder structure.
+1. Update Python Versions: Replaces occurrences of the source Python version with the target version throughout the folder.
+1. Update Lock Files: Executes `pipenv lock` to regenerate lock files based on the new Python version.
+
+If `pipenv lock` encounters errors, manual intervention is required to resolve compatibility issues between dependencies. Review the errors reported by `pipenv` and adjust the dependencies as needed.
+
+### Examples
+
+Create a Python 3.12 version based on the Python 3.9 version for each one that is in the `./base` directory:
+
+```sh
+python scripts/new_python_based_image.py --context-dir . --source 3.9 --target 3.12 --match ./base
+```
+
+Create a Python 3.11 version based on the Python 3.9 versions for each one that is in the `./jupyter/rocm` directory:
+
+```sh
+python scripts/new_python_based_image.py --context-dir . --source 3.9 --target 3.11 --match ./jupyter/rocm
+```
+
+Create a Python 3.11 version based on the Python 3.9 version for each one in the repository with `DEBUG` logs enabled:
+
+```sh
+python scripts/new_python_based_image.py --context-dir . --source 3.9 --target 3.11 --match ./ --log-level DEBUG
+```
