NVIDIA/dgx-spark-playbooks ? reverse-engineered prompt

Build me a clean, browsable playbook site or notebook collection for NVIDIA DGX Spark that helps people set up and run AI and ML projects on the device.

I want it to feel like a practical guide library, with one place to find step by step walkthroughs for things like local LLMs, fine tuning, ComfyUI image and video generation, RAG apps, multi GPU and multi node setups, remote access, VS Code setup, and other common DGX Spark workflows. Each playbook should have a simple overview, what you need first, the steps to follow, troubleshooting tips, and a small example at the end.

Make the experience easy to navigate, with a homepage that groups the playbooks by topic and makes it obvious what each one is for. Keep the writing friendly and clear for someone who is not deeply technical. If you need to check current docs or best practices online, go ahead and look them up.
