Worked on enhancing developer experience in the yorkie-team/yorkie repository by delivering a focused update to the Pub-Sub documentation. The effort centered on clarifying code links and refining event type descriptions to accurately reflect the current Pub-Sub implementation on the Yorkie server. Using Go and Markdown, the developer prioritized maintainability and traceability, ensuring that documentation changes were clearly linked to relevant code and commit history. This documentation-centric approach aimed to streamline onboarding for new contributors and reduce the risk of misconfiguration. No bugs were addressed during this period, with all work dedicated to backend documentation and developer clarity.
