During December 2024, Jiwon Ahn focused on enhancing documentation for the AlmSmartDoctor/study-2024-10-restful-web-api repository. Jiwon improved the README by providing a detailed comparison between Swagger and OpenAPI Generator, offering guidance on selecting appropriate API tooling for different scenarios. The documentation also clarified distinctions between HTML and XHTML, covering syntax, DOM manipulation, error handling, and extensibility. Using Markdown and technical writing skills, Jiwon aimed to reduce onboarding friction and improve maintainability by aligning documentation with project standards. The work established a clear reference for future API-tooling decisions, supporting cross-team collaboration and ensuring consistent technical communication within the project.
