Updation of readme.md file

## Issue: Update README.md for Improved Clarity and Structure

### Description:
The current `README.md` file can be enhanced for better clarity and structure. The following updates are proposed:
- Add a **Contributing** section with a link to the newly added `CONTRIBUTING.md`.
- Revise existing sections for better readability and organization.
- Ensure that the README effectively highlights project features and encourages contributions.

This update will make the README more user-friendly, informative, and aligned with the latest project changes.
