Worked on the microsoft/PhiCookBook repository to enhance documentation for the Phi-4 model family, focusing on correcting and validating Hugging Face links for the Phi-4-reasoning and Phi-4-mini-reasoning models. Used Markdown to update cross-links throughout the documentation, improving navigation and ensuring users can reliably access relevant model resources. Leveraged Git-based collaboration to maintain traceable and accountable changes, linking updates directly to specific commits. This documentation update aimed to accelerate onboarding for new users and reduce support queries by providing clearer, more accurate information. Demonstrated strengths in documentation craftsmanship, cross-link validation, and collaborative workflows within a version-controlled environment.
