Worked on enhancing the Transit Secret Engine API documentation within the hashicorp/web-unified-docs repository, focusing on clarifying the semantics of the key_version parameter. Used Markdown and documentation best practices to specify that key_version must be unset or greater than or equal to min_encryption_version, ensuring correct key usage across different Vault versions. Incorporated feedback from code review to finalize the update, aiming to reduce onboarding time and minimize support queries for developers integrating Transit. The work improved cross-version interoperability and provided clearer guidance for users, demonstrating attention to detail and a methodical approach to technical documentation and developer experience.
