Worked on enhancing the Penguins_chapter.qmd documentation within the MarieEtienne/2024_MODE_OCR repository, focusing on improving readability, layout, and overall clarity for data consumers. Applied technical writing and proofreading skills to refine dataset descriptions, introduce color-coded headings, and add new sections that facilitate faster onboarding and reduce support questions. Utilized Quarto Markdown and R to ensure the documentation met high standards of maintainability and accessibility. The work emphasized layout design and version-controlled documentation, addressing ambiguity and supporting better data understanding. No major bugs were fixed during this period, as the primary focus remained on elevating documentation quality and usability.
