 - `--controlnet`: ControlNet models specified with this option are used in image generation. Use this option in the format `--controlnet lllyasviel/sd-controlnet-mlsd lllyasviel/sd-controlnet-depth` and make sure to use `--controlnet-inputs` in conjunction.
 - `--controlnet-inputs`: Image inputs corresponding to each ControlNet model. Please provide image paths in same order as models in `--controlnet`, for example: `--controlnet-inputs image_mlsd image_depth`.
 
+Here's an example Python program using the weights found from [mixed bit palettization](https://huggingface.co/apple/coreml-stable-diffusion-mixed-bit-palettization/tree/main/coreml-stable-diffusion-xl-base_mbp_4_50_palettized):

+The code assumes you've downloaded the `./coreml-stable-diffusion-mixed-bit-palettization_original_compiled/compiled/` files to the same directory.
+
+The script will download another model and then re-compiled the previously compiled `.mlmodelc` files too. It will take a while on the first run, and then be faster after.
