Worked on the ClickHouse/clickhouse-docs repository to deliver a comprehensive update to the Helm documentation for the 2.x release, with careful attention to maintaining backward compatibility for users on 1.x. Focused on providing clear migration guidance and minimizing upgrade friction, the work involved restructuring and enhancing documentation written in Markdown and YAML. Leveraged expertise in Helm and Kubernetes to ensure technical accuracy and consistency throughout the documentation. No major bug fixes were required during this period, allowing for a concentrated effort on improving clarity, navigation, and support for both new and existing users transitioning between Helm chart versions.
