Worked on enhancing CUDA documentation within the ustclug/Linux201-docs repository, focusing on improving guidance for Docker-based workflows and NVIDIA driver or CUDA installation. The contribution involved restructuring existing Markdown documentation to remove outdated information and clarify installation steps for different user needs, making the onboarding process more accessible for developers working with GPU-enabled environments. Leveraging skills in CUDA, Docker, and technical documentation, the work emphasized reproducibility and maintainability by providing targeted setup instructions and environment configuration tips. No bugs were addressed during this period, as the primary value delivered was in documentation clarity and improved developer experience through well-organized, actionable content.
