Andrea contributed to the huggingface/hub-docs repository by updating the datasets-adding.md documentation to explicitly include PDF as a supported file type. This work focused on aligning the documentation with the actual product capabilities, aiming to reduce user confusion and lower support requests related to data ingestion. Andrea used Markdown to ensure the documentation was clear and accessible, leveraging strong skills in technical writing and documentation management. The update was prepared as a release-ready change, supporting user onboarding and workflow accuracy. While the contribution was limited in scope, it addressed a concrete need for clarity in the documentation and improved user experience.
