During June 2025, Burui Wen focused on enhancing documentation for the IntensiveCoLearning/ethereum-protocol-4 repository, consolidating and updating the README to align with EPF Mandarin Group’s fourth iteration branding. Using Markdown and leveraging strong documentation skills, Burui integrated detailed program information and linked EPF/EPFsg initiatives to relevant guides and the project wiki, improving onboarding and resource discoverability for partners and contributors. The work included correcting event registration dates to reflect updated schedules, ensuring accuracy and consistency across project materials. All contributions were tracked through successive README commits, providing clear change history and supporting process alignment without requiring codebase modifications.
