Richard Shepherd consolidated and expanded the NPDA platform user guide in the rcpch/national-paediatric-diabetes-audit repository, focusing on improving onboarding, data submission, and visualization workflows. He authored comprehensive documentation in Markdown, detailing account creation for multiple user roles, login and two-factor authentication, and CSV data submission formatting. His technical writing clarified data quality checks, error reporting, and the process for adding or editing visits via patient questionnaires. Richard also enhanced guidance for Unit and Patient Report sections, including interactive chart and tooltip usage. The work, delivered through five targeted commits, demonstrated depth in documentation and a methodical approach to user enablement.
