Worked on the mermaid-js/mermaid repository to enhance the onboarding and developer experience by updating the getting-started documentation. Focused on aligning installation instructions with Node.js v20+ LTS and supporting multiple package managers, including npm, pnpm, and yarn. The approach involved removing outdated steps, such as the global yarn installation, and introducing explicit step numbering for clarity. Utilized Markdown for documentation and applied skills in Node.js and package management to ensure the setup process is current and accessible. No bug fixes were reported during this period, with the primary contribution centered on improving documentation accuracy and streamlining the initial setup process.
