Worked on enhancing documentation for the drshahizan/learn-github repository, focusing on improving onboarding and developer experience. Developed a comprehensive README for the exercise/lanazlan1 directory, introducing structured headers, a Markdown table of employee data, and expanded content with KaTeX for mathematical rendering and Mermaid for diagram support. Emphasized maintainability and clarity by progressively updating documentation through multiple commits, ensuring a scalable foundation for future contributors. Utilized Markdown, KaTeX, and Mermaid to deliver clear, accessible documentation without addressing code bugs. The work reduced onboarding time and improved knowledge transfer, supporting a more efficient and collaborative development environment within the repository.
