 # ComfyUI-ApplyResAdapterUnet
-ComfyUI node to apply the ResAdapter Unet patch for SD1.5 models
+
+ComfyUI node to apply the ResAdapter Unet patch for SD1.5 models.
+
+See https://github.com/bytedance/res-adapter for explanation and link to download the LoRA and unet patch.
+
+## Usage
+
+### SDXL
+
+For SDXL, you only need the LoRA (as far as I know) so a dedicated node is unnecessary: just load the LoRA as usual. You don't need this repo.
+
+### SD 1.5
+
+* Put the `resolution_normalization.safetensors` model in `models/unet`
+* Patch the model with the `ApplyResAdapterUnet` node, load the `resolution_lora.safetensors` LoRA normally.
+
+You can experiment with different unet and LoRA strengths.
+I haven't tested it extensively, but at resolutions above 1024x1024 using full strength doesn't seem to work well (and in fact may be worse than nothing).
+It's also possible to combine ResAdapter with other techniques such as Kohya Deep Shrink (AKA `PatchModelAddDownScale`).
+
+## Example Workflow
+
+Workflow with included ComfyUI metadata:

+
+(Simple demonstration, I made no effort to get a pretty picture.)
