Code Review

This pull request significantly improves the documentation by refactoring the main README files and organizing content into more specific documents. This makes the information easier to find and digest for users. The changes are well-structured and applied consistently across both English and Chinese versions. However, I've identified a high-severity security concern in the new quick_start.md files. The example docker run commands suggest mounting the entire host /home directory, which poses a security risk. My review includes suggestions to scope down the volume mounts to enhance security for users who might copy-paste these commands.

Code Review

This pull request significantly refactors the documentation by reorganizing content from the main README into more detailed pages under the docs/ directory. The changes improve the structure and readability of the documentation, making it easier for users to navigate. I've identified a couple of high-severity issues in the new quick_start.md files where the docker run command for NPU environments is inconsistent and likely incorrect, which could cause confusion for users. I've provided suggestions to fix these commands.
