 ## Installing a model
 If you've downloaded a model, you can make it available to Stable Diffusion UI:
 - Copy the model file to `C:\stable-diffusion-ui\models\stable-diffusion`. The file should have the suffix `.ckpt` or `.safetensors`.
+- If the model comes with a `.yaml` file, please place that yaml file next to the model, with the same name. For e.g. if the model is `some-model.ckpt`, the yaml file should be `some-model.yaml`, placed next to it in the same folder.
 - Reload your browser page. The model should be listed in the "Models" section in the image settings:
