Jianfeng Chi enhanced the documentation for the meta-llama/PurpleLlama repository by updating and standardizing citations and references for the Llama Guard 3 Vision project. Focusing on Markdown-based artifacts such as README.md and MODEL_CARD.md, Jianfeng improved the traceability and credibility of the documentation by including detailed author information, publication details, and arXiv links. The work involved multiple targeted commits to ensure consistency across all relevant files. Leveraging skills in technical writing and documentation, Jianfeng addressed the need for transparent and verifiable references, resulting in clearer project artifacts. The scope was focused, with depth in documentation quality rather than breadth of features.
