Contributed to the alibaba/MNN repository by delivering a focused documentation enhancement aimed at improving the clarity of the command line interface help text. The work involved identifying and correcting typographical errors and refining the descriptions of CLI options to provide clearer guidance for users. Using Python and command line interface expertise, the developer aligned the documentation with established standards to support better onboarding and reduce user confusion. This targeted update did not address bug fixes but instead prioritized user experience and maintainability, resulting in a single-commit feature that strengthens the usability of the CLI for both new and existing users.
