Worked on enhancing the DataDog/dd-trace-dotnet repository by delivering improved MacOS build setup and troubleshooting documentation. Focused on streamlining developer onboarding, the work clarified build steps, introduced Visual Studio Code as a supported development environment, and provided actionable guidance for resolving common macOS build errors. Using Markdown for documentation, the updates aimed to reduce setup friction and accelerate contributor ramp-up by making the build process more transparent and accessible. No bugs were reported or fixed during this period, with efforts concentrated on documentation quality and cross-platform reliability. The contribution strengthened the repository’s support for MacOS development workflows.
