Add more detailed setup instructions for local testing

[tugascrown204]

Issue

The current README provides a brief overview of how to test the code, but it lacks detailed setup instructions for users who may not be familiar with the environment requirements or dependencies needed for successful local testing.

Suggestion

It would be beneficial to include a step-by-step guide that outlines the prerequisites for testing the code, such as:

1. Python version required
2. Any necessary packages or libraries that need to be installed
3. How to run tests locally, including any commands or configurations that are needed

This would greatly enhance the usability of the repository for newcomers and help ensure that they can successfully run the examples from the book.
