Huangfu updated the attendee information page for the COSCUP/2025 repository, focusing on content management to improve event logistics and attendee guidance. The work involved clarifying the number of buildings used for activities, expanding the Hacking Corner description to include an additional location, and refining the wording for attendee services to reduce confusion and support queries. Huangfu implemented these changes in a single, well-scoped commit using Markdown, ensuring concise and maintainable documentation. The update addressed specific user experience issues by making event information clearer and more accessible, demonstrating careful attention to detail and a targeted approach to content-driven development.
