Worked on enhancing the coscene-io/docs repository by delivering comprehensive documentation updates focused on Data Collection and Diagnostic Rules. The effort centered on clarifying permissions, data formats, and rule group management to support both users and contributors. Using Markdown and technical writing skills, the developer consolidated guidance for rule creation, device event monitoring, and data diagnosis actions, improving onboarding and operational consistency. The documentation was further refined with internationalization support and improved anchor navigation, increasing localization readiness and maintainability. This work established a clear, standards-aligned foundation for future rule-related features, addressing documentation gaps and streamlining the onboarding process for new contributors.
