[minzhenw490-pixel]

Documentation Improvement Suggestion

Problem Description

The repository README only introduces how to clone and install the project, but there is no specific running demonstration for any script. New Python learners don’t know how to execute the sample scripts after downloading the repo.

Suggested Optimization

Add a general running guide under Quick Start section:

1. Enter the corresponding script folder
2. Run the script with command:

python script_name.py
