2

## Summary I translate the manual into zh-CN. ## How it was tested? I follow the instruction of how to build the manual locally, and webstie turns out work properly.

## Summary I translate the README.md into zh-CN. ## How it was tested? I test the chinese button on the README.md from github.com, which turns out work properly.

Hello, have you considered adding localization to the official website? I believe I can handle the Chinese translation part.
