Can you give me a readme

[guoxin-xin]

Hello!
When reviewing the code file you provided, I found that I still have doubts about the execution order of the code. In order to gain a deeper understanding of the project structure and logic, I kindly request that if possible, you provide a README file. This document will be of great benefit to me in organizing the code logic and execution process.
Looking forward to your reply and thank you for your help!
