Worked on improving documentation quality in the pingcap/docs repository by addressing inconsistencies in the casing of encoding format keys. Focused on standardizing the terms TableID and IndexID throughout the Markdown documentation to align with the TiDB codebase, thereby reducing potential confusion for users and maintainers. Applied technical writing skills to ensure clarity and maintainability, and utilized disciplined version control practices to deliver a targeted, traceable fix. The work involved identifying and correcting a specific typo, ensuring that documentation accurately reflected the intended naming conventions. This approach contributed to better documentation standards and improved the overall user experience for TiDB documentation.
