- Added a "Start Here" section in both English and Chinese README files to guide new users on running the project locally and exploring its features. - Introduced backend conventions for date and serialization handling, clarifying the use of Pydantic v2 and PostgreSQL. - Updated the "Quick Start" section with detailed steps for first-time local setup, including environment requirements and backend setup instructions. - Improved overall structure and clarity of documentation to facilitate better understanding for developers and contributors.
