Liang Shuangde focused on enhancing the developer experience for the plotly/graphing-library-docs repository by updating documentation related to Plotly.js installation. The work involved clarifying the installation steps, specifically replacing the outdated yarn install plotly.js-dist command with the recommended yarn add plotly.js-dist, aligning the guide with current Yarn best practices. This targeted change, implemented using HTML and documentation skills, aimed to streamline onboarding for new contributors and reduce setup errors. The update was delivered as a single, clean commit, making it easy to review and revert if necessary. No bugs were addressed, and the scope remained limited to documentation improvements.
