Worked on the rust-lang/rustc-dev-guide repository to enhance documentation quality and contributor experience. Focused on cleaning up the compiler-src.md file by identifying and fixing broken internal links, ensuring they correctly referenced the intended compiler-src chapter. This targeted documentation update, implemented using Markdown and leveraging strong documentation skills, improved navigation and reduced confusion for new contributors. The changes streamlined onboarding by making cross-references more reliable, which in turn lowered maintenance overhead and minimized navigation errors. Although no new features were added, the work addressed a key pain point in documentation integrity, supporting smoother contributor flow and faster issue resolution within the project.
