Worked on consolidating the course structure in the huggingface/course repository, focusing on improving documentation and streamlining the learner experience. The main feature involved removing references to chapters 10-12 and centering the course content around chapter 9, which guides users in building and sharing model demos on the Hugging Face Hub. This targeted refactor, implemented using Markdown, clarified the learner path and reduced unnecessary complexity in the course overview. By enhancing documentation quality and repository organization, the work aimed to improve onboarding, learner outcomes, and maintainability, ensuring the course remains focused and aligned with hub-based demonstrations for future updates.
