Worked on enhancing the huggingface/hub-docs repository by updating the datasets-adding.md documentation to explicitly include PDF as a supported file type. This change aligned the documentation with the actual product capabilities, reducing user confusion and anticipated support requests. The work focused on clear, user-oriented documentation practices using Markdown, ensuring that onboarding and data ingestion workflows are accurately represented. No bug fixes were required during this period, as the primary contribution centered on feature documentation. The update was prepared for release review, reflecting a methodical approach to maintaining documentation quality and supporting users with up-to-date, actionable information about file format support.
