Worked on the RaspberryPiFoundation/editor-api repository to enhance entity-relationship diagram (ERD) workflows by introducing clear ERD generation guidance and a dedicated configuration file for naming conventions. Focused on improving database design documentation, the developer removed outdated ERD materials and updated the README to reflect the current process, ensuring contributors have accurate, up-to-date instructions. Collaborated with Copilot to co-author documentation improvements, aligning with repository standards and best practices. Leveraged Docker for environment consistency and utilized Markdown and YAML to structure documentation and configuration. The work addressed maintainability concerns and streamlined the ERD modeling process for future development and onboarding.
