Enhance Project Documentation

[xzyaoi]

The project currently has minimal documentation, which could make it difficult for new contributors to get started and understand the system architecture.

Suggested improvements:

1. Add comprehensive README.md with:

   • Project overview and goals
   • Installation instructions
   • Quick start guide
   • Architecture overview
   • Configuration guide
   • Development setup instructions

2. Add API documentation:

   • Document the public APIs in each major module
   • Include usage examples
   • Document configuration options

3. Add architectural documentation:

   • System components and their interactions
   • Data flow diagrams
   • Deployment architecture
   • Performance considerations

4. Add contribution guidelines:

   • Code style guide
   • PR process
   • Testing requirements
   • Issue reporting guidelines

This will help new contributors understand the project better and make it easier to maintain and extend the codebase.
