Worked on establishing the initial documentation framework for diagramming within the eunbi-kim/24_2_W_SeProj repository, focusing on maintainability and future extensibility. Created two XML-based mxlibrary placeholder files to bootstrap potential modeling capabilities, providing a clear structure for future documentation enhancements. Subsequently, performed targeted cleanup by removing an unused placeholder file, streamlining the documentation and reducing confusion for new contributors. The work emphasized documentation skills and XML proficiency, ensuring that onboarding processes are more straightforward and that the groundwork is set for future diagramming features. Overall, the contributions addressed both immediate organizational needs and long-term project scalability within the documentation.
