 # docker-comfyui
 
-Build and run ComfyUI in a container. This build targets NVIDIA by basing it
-on the CUDA PyTorch runtime image. The only extra dependencies needed are
-`git`, to clone the official ComfyUI repository, and `build-essential` for
-`gcc`, which Triton requires. The image pulls a specific, pinned ComfyUI
-version via the `COMFYUI_VERSION` build arg. The build merely shallow-clones
-the repo and installs its requirements with `pip`. Kept intentionally simple.
