Issue: Missing Contribution Guidelines and Repository Setup Instructions

[sadique-2004]

The current README.md is welcoming and beginner-friendly but lacks a Contribution Guidelines section. This section would provide potential contributors with a clear roadmap for how to contribute, the rules they need to follow, and how to set up the repository locally for testing. Providing these details ensures that new contributors can quickly understand the process and avoid mistakes when making their first pull request.
