Worked on the MicrosoftEdge/MSEdgeExplainers repository to deliver two developer-facing documentation features focused on API clarity and standards alignment. Updated the API proposals documentation by refining the README to reflect current development priorities, specifically removing outdated entries and adding new API details. Enhanced the ElementInternals.type explainer by introducing comprehensive documentation, linking to relevant WHATWG tracking issues, and expanding coverage for custom button attributes. Emphasized technical writing and API design using Markdown and web components, ensuring documentation consistency across the project. The work prioritized onboarding and adoption, laying a foundation for future API changes without addressing high-severity bugs during this period.
