Azlan enhanced the documentation for the drshahizan/learn-github repository, focusing on improving onboarding and developer experience. He created and iteratively updated the exercise/lanazlan1 README, introducing structured headers, a Markdown table of employee data, and expanded content with KaTeX for math rendering and Mermaid for diagrams. His work leveraged Markdown, KaTeX, and Mermaid to establish a scalable documentation foundation, prioritizing clarity and maintainability. No major bugs were addressed, as efforts centered on documentation quality. These enhancements reduced onboarding time and improved knowledge transfer, providing clearer contributor guidelines and supporting future documentation growth within the repository’s Git-based workflow.
