Add a worked example using simulated data to README.md

[cjerzak]

The README.md file currently lacks a worked example that demonstrates how to use the package. Adding a worked example, potentially using simulated data, will help new users understand the workflow and implementation quickly.

Tasks:

• Create simulated data if real data is not available or appropriate.
• Develop a step-by-step worked example demonstrating the usage of the package.
• Add this example to the README.md for clear visibility and accessibility.

Benefits:

• Improves documentation quality.
• Makes onboarding easier for new users and contributors.
• Provides a reference for typical usage and expected outcomes.
