Documentation Improvement

### **Description:**
The current documentation for the LibraryMan project lacks clarity in certain areas, making it difficult for new contributors to understand the codebase and contribute effectively. This issue involves updating and enhancing the existing documentation to improve the contributor experience.

### **Tasks:**
- Review the existing documentation and identify areas that need improvement.
- Add detailed explanations of key features and modules within the project.
- Ensure proper formatting and structure for easy navigation.
- Include steps for setting up the development environment and running the project locally.
- Create guidelines on how to contribute (pull request process, coding standards, etc.).

### **Expected Outcome:**
- The documentation should be comprehensive and easy to follow for new contributors.
- Contributors should be able to understand the project's structure, code logic, and contribution process without confusion.
