Worked on enhancing the noir-lang/noir-bignum repository by overhauling its documentation to improve developer onboarding and clarify usage expectations. Focused on updating the README to provide a detailed overview of the BigNum and RuntimeBigNum types, including their methods and parameter sets, and supplemented this with practical usage examples and benchmark data. Emphasized technical writing and documentation skills, using Markdown and Rust to ensure accuracy and clarity. The work aimed to provide measurable performance context for downstream projects and streamline the onboarding process, with all changes version-controlled and documented through a dedicated commit, reflecting a methodical and impact-driven approach to open-source contribution.
