Guo Haowen developed and refined the Ghw2066 onboarding documentation for the IntensiveCoLearning/Ten-Days-on-Crypto-Ideology repository, focusing on creating a clear and reusable onboarding process for new contributors. Using Markdown and configuration skills, he structured the guide to include personal introductions, goals, contact information, daily notes, and timezone guidance. Through multiple version-controlled iterations, he simplified timezone options, tightened the introduction, and updated contact details, ensuring the documentation remained concise and relevant. This work established a maintainable documentation pattern that streamlines onboarding, reduces friction for new team members, and aligns with project standards, demonstrating thoughtful attention to clarity and process improvement.
