Worked on enhancing documentation for the TianxingChen/Embodied-AI-Guide repository, focusing on improving the readability and structure of the project’s README file. Applied Markdown skills to migrate heading formatting from an asterisk-based style to hash-based headings, creating a clearer visual hierarchy that supports faster onboarding and easier navigation for new contributors. The update was delivered as a single, traceable commit to maintain a clean project history. By refining the documentation, the developer contributed to a smoother developer experience and reduced ramp-up time for collaborators. The work centered on documentation best practices and effective use of Markdown for open-source project onboarding.
