# Comfyui Docs

> ComfyUI documentation — node-based Stable Diffusion GUI and workflow engine. Covers 67 built-in nodes (CheckpointLoader, KSampler, CLIPTextEncode, VAEDecode, ControlNet, LoRA, IPAdapter, etc), custom node development (Python API, data types, UI widgets, backend extension), workflow tutorials (text-to-image, image-to-image, inpainting, ControlNet, LoRA, SDXL, Flux, upscaling, video, audio, 3D), ComfyUI Manager, Registry (publishing/versioning nodes), Comfy CLI, API reference, cloud deployment, installation (Desktop/manual/Docker), interface guide, and troubleshooting. USE THIS SKILL WHEN the user asks about ComfyUI nodes, workflows, custom node development, ComfyUI API, or Stable Diffusion pipeline configuration.
