The documentation incorrectly states that pnpm will be automatically managed by mise. However, the mise.toml file only includes Node.js and Rust, not pnpm. This should be updated to match the correct information from README.md line 50, which states that pnpm must be installed separately.

Suggested correction: "이제 프로젝트 디렉토리에서 자동으로 올바른 버전의 Node.js와 Rust가 사용됩니다. pnpm은 별도로 설치해야 합니다."

Suggested change

	이제 프로젝트 디렉토리에서 자동으로 올바른 버전의 Node.js, pnpm, Rust가 사용됩니다.
