In January 2025, Jamie Cates enhanced the wellcomecollection/docs repository by introducing a centralized SUMMARY.md file within the Architecture Decision Records directory. This addition established a Markdown-based documentation pattern, organizing architectural decisions into a searchable table of contents to improve discoverability and onboarding for new team members. Jamie focused on documentation as the primary technical skill, leveraging Markdown to enforce consistent standards and support architectural governance. The work addressed the need for clearer cross-team communication and maintainability, providing a structured reference for best practices. No bugs were fixed during this period, and the contribution was limited to documentation improvements.
