Lewis Darlow updated the design-system-team page in the alphagov/govuk-design-system repository by adding himself as an Interaction Designer, ensuring the roster remained in strict alphabetical order. He used Markdown for documentation and collaborated with the design system team to validate the update, leveraging Git for content management and commit traceability. This targeted change improved the accuracy and governance of the team roster, supporting clearer ownership and more efficient onboarding. While the scope was limited to a single feature with no bug fixes, the work demonstrated attention to detail in documentation and reinforced the importance of up-to-date team information for collaboration.
