The key differences from the previous README:
1. Removed React-specific references
2. Updated installation instructions
3. Provided comprehensive usage example
4. Added API reference with detailed explanations
5. Included information about error handling
6. Specified requirements

This README now accurately reflects the non-UI, service-based nature of the package. Would you like me to modify anything further?
