Worked on the google/A2A repository to enhance contributor onboarding by updating the README with clearer, governance-ready contributing guidelines. Focused on documentation best practices, the update restructured instructions into concise bullet points and adopted a more welcoming tone to lower entry barriers for new contributors. Used Markdown to improve formatting and readability, ensuring that participation steps were easy to follow and aligned with open-source collaboration standards. No major bugs were addressed during this period, as the primary emphasis was on refining user-centered documentation and disciplined commit messaging to accelerate external contributions and reinforce project governance for the A2A protocol.
