Section/Topic

"The main goal is to provide a complete, localized entry point for Chinese developers. Specifically, I believe the following sections need the most 'localization' to improve clarity: Commands & Usage: Precise translation of Slash Commands (like /view vs /edit) ensures users understand the tool's intent without language barriers. Security & Permissions: This is a critical area. Clearer Chinese explanations of how Claude Code interacts with the local file system will help users build trust. Setup & Environment: Providing instructions in Chinese for API configuration and environment variables will significantly lower the onboarding friction for the local community."

What's Wrong or Missing?

Currently, the documentation is only available in English. While the content is excellent, a native Chinese version is missing, which creates a couple of issues:

High Onboarding Barrier: Many developers in the Chinese community may find it time-consuming to digest complex technical details (like security permissions and token management) in a second language.

Command Ambiguity: Certain slash commands (e.g., /compact, /view) need precise localized explanations to ensure users use them correctly without misunderstanding their intent.

Community Reach: The lack of a README_zh-CN.md limits the discoverability and adoption of Claude Code among the large Chinese developer ecosystem.

Suggested Improvement

I propose adding a high-quality Simplified Chinese version (README_zh-CN.md). The translation will focus on localizing technical terms while maintaining the original's professional tone.
