Worked on improving documentation hygiene in the EbookFoundation/free-programming-books repository, focusing on the Rust section. Addressed a broken PDF link for the Turkish resource 'Rust'a Giriş', ensuring users have access to valid learning materials. Removed an invalid empty link placeholder and cleaned up unavailable content to maintain accuracy and reduce clutter. Adjusted Markdown formatting to resolve linter errors, enhancing readability and future-proofing the documentation against build issues. Utilized content management and documentation skills, with a strong emphasis on Markdown syntax and linting practices. The work contributed to a more reliable and user-friendly experience for readers seeking Rust programming resources.
