Developed comprehensive Browser Compatibility Policy Documentation for the mdn/fred repository, focusing on clarifying browser support expectations for both users and developers. The work involved drafting detailed Markdown documentation that formalizes the definition of “supported” browsers and versions, establishing clear policy scope and version coverage. By leveraging strong documentation skills and expertise in Markdown, the developer improved transparency and consistency across MDN’s guidance. The documentation was implemented through a dedicated commit, ensuring the new policy is easily accessible and maintainable. This contribution addressed the need for explicit compatibility standards, supporting better communication and alignment within the MDN project ecosystem.
