Azlan enhanced documentation for the drshahizan/learn-github repository, focusing on improving onboarding and knowledge transfer for new contributors. He created and iteratively refined the exercise/lanazlan1 README, introducing structured headers, a Markdown table of employee data, and expanded content with KaTeX for mathematical notation and Mermaid for diagram rendering. His work leveraged Markdown, KaTeX, and Mermaid, demonstrating proficiency in documentation tooling and Git-based workflows. By prioritizing clarity and maintainability, Azlan established a scalable documentation foundation that reduced onboarding time and clarified contributor guidelines. No major bugs were addressed, as efforts centered on documentation quality rather than codebase changes.
