Worked on the MicrosoftDocs/azure-compute-docs repository to update the metadata security protocol compatibility matrix, ensuring documentation accurately reflected current platform support. Focused on aligning the listed operating systems and architectures with actual platform capabilities by removing Windows ARM64, adding Ubuntu ARM64, and discontinuing Flatcar support due to its read-only nature. Used Markdown to revise overview documentation, clarifying supported environments and reducing potential confusion for customers and support teams. Demonstrated strong documentation skills by enhancing the clarity and reliability of technical references. The work contributed to more accurate guidance for users and streamlined support processes, though it did not involve direct bug fixes.
