Worked on improving documentation quality for cluster node operations in the ytsaurus/ytsaurus repository, focusing on enhancing accuracy and reducing ambiguity for operators. Addressed a terminology issue by correcting the typo 'decomimssion' to 'decommission' throughout the relevant Markdown documentation, ensuring consistency and professionalism in technical references. The update was tracked through a dedicated commit and merged pull request, demonstrating a disciplined approach to documentation management. Utilized Markdown as the primary language and applied strong documentation skills to clarify operational procedures, ultimately supporting better user understanding and minimizing potential support queries related to cluster node operations within the project.
