Worked on the CSCfi/csc-user-guide repository to enhance Roihu documentation, focusing on security and data access clarity. Delivered updates that introduced a multi-factor authentication requirement notice for Roihu services and added direct links to the National Library of Finland open material dataset, improving user guidance and data discoverability. Used markdown and technical writing skills to clarify which datasets are currently available and documented the context for data transfers, including Puhti accessibility. The work emphasized clear communication of security requirements and data availability, resulting in more comprehensive and user-friendly documentation for Roihu users. No bug fixes were recorded during this period.
