The fact you're asking for commands tells me you're very new to this.

For niche things like guro you're gonna need a customized local setup. Don't expect cloud hosting stuff (like civit and others) to facilitate guro related stuff. They vaguely tolerate adjacent content but purge anything explicit.

So I suppose the first question is can you run SD locally?
Current models need a GPU with 8gb VRAM (minimum), but you'll be more comfortable with 12GB and above.

It's also better if you have an NVIDIA GPU since this stuff works on CUDAS. There are solutions in the form of ZLUDA (kind of a CUDA emulation solution for AMD cards), but this is slower.

So first confirm you got usable hardware
