This pull request significantly enhances the project's README.md to make it more professional, informative, and welcoming for new users.

The following sections have been added or improved as per the issue requirements:

• A clear Features list.
• Detailed step-by-step Installation instructions.
• A simple Usage Example to demonstrate the core functionality.
• A placeholder for API Documentation.
• A basic Troubleshooting guide for common problems.
• Professional badges for the license and repository activity.

This new documentation should make it much easier for users to get started with the project.
