Worked on improving documentation quality for the supabase/pg_graphql repository by addressing a syntax issue in the Apollo Usage Guide. Focused on enhancing onboarding and reducing misconfiguration risk, the developer identified and corrected a missing comma in a Markdown configuration example. This targeted documentation patch ensured that Apollo usage scenarios were accurately represented, aligning with established documentation standards and best practices. The work involved careful attention to detail and clear commit messaging, contributing to lower support overhead and smoother integration for new users. The contribution centered on documentation skills and proficiency with Markdown, without introducing changes to production code or features.
