Worked on enhancing the Cosmos DB onboarding documentation within the MicrosoftDocs/azure-databases-docs repository, focusing on the Per Partition Automatic Failover (PPAF) preview feature. Addressed a documentation bug by correcting broken and unclear links in the Markdown files, ensuring users could reliably access the PPAF preview registration and related troubleshooting scripts. Improved Markdown formatting and added direct links to relevant GitHub resources, streamlining the onboarding process for new users. This work emphasized documentation quality and clarity, reducing potential support queries and aligning with repository standards. Utilized skills in technical writing, documentation best practices, and Markdown to deliver these improvements.
