Worked on improving documentation accuracy for the GreptimeTeam/docs repository, focusing on Helm chart authentication configuration. Addressed a mismatch in the authentication example by updating documentation to use the correct 'username' field, ensuring alignment between the documentation and actual Helm chart values. This change reduced the risk of deployment misconfigurations and improved the onboarding experience for new users. Collaborated with both documentation and authentication teams to verify the update reflected real-world usage. Utilized Markdown for documentation and applied configuration management skills to maintain consistency. The work emphasized clarity and correctness, helping to prevent potential support issues related to authentication setup.
