Worked on modernizing documentation for the techeer-sv/2024-Team-Joe-backend-study repository, focusing on enhancing the structure and usability of project docs. Added explicit chapter titles and navigational links for chapters 07 through 10, using Markdown to improve onboarding and content discoverability for new contributors. The approach emphasized clear organization and maintainability, with well-scoped commits that set a foundation for future documentation growth. No codebase changes were made, as the work centered on documentation best practices and standardization. This effort leveraged skills in technical writing and documentation management, contributing to a more accessible and navigable knowledge base for the project.
