So the first thing you do is a git clone https://github.com/comfyanonymous/ComfyUI. Then cd ComfyUI/custom_nodes. Then issue git clone https://github.com/ltdrdata/ComfyUI-Manager. Last thing to do, navigate to ComfyUI again and issue pip install -r requirements.txt. So I’m skipping some of the PyTorch stuff and that’s important and all, but this is just a real condensed summary that you’re going to have to fill the gaps of. Sorry. I might be too stoned to do a proper doc on it, but it’ll get you pointed in the right direction.
