Worked on the apollographql/apollo-client repository to refresh and clarify documentation for the GraphQL Jest transformer integration. Focused on improving the onboarding experience for developers by updating the webpack integration docs, ensuring they reference the new jest-graphql-transformer and accurately reflect current tooling. Used Markdown to restructure guidance, aiming to reduce confusion caused by outdated references to previous transformers. This documentation update supports contributors and CI pipelines by streamlining setup and minimizing support requests related to GraphQL transformation in Jest. The work emphasized clear communication and precise technical documentation, leveraging skills in developer onboarding and documentation best practices.
