+## Settings
+
+You can change the configs of inpainting process in the settings interface of the web page.

+###  Inpainting Model
+
+Select the inpainting model to use, and set the configs corresponding to the model.
+
+LaMa model has no configs that can be specified at runtime. 
+
+LDM model has two configs to control the quality of final result:
+1. steps: You can get better result with large steps, but it will be more time-consuming
+2. sampler: ddim or [plms](https://arxiv.org/abs/2202.09778). In general plms can get better results with fewer steps
+
+
+### High Resolution Strategy
+
+There are three strategies for handling high-resolution images.
+
+- **Original**: Use the original resolution of the picture, suitable for picture size below 2K.
+- **Resize**: Resize the longer side of the image to a specific size(keep ratio), then do inpainting on the resized image. 
+The inpainting result will be pasted back on the original image to make sure other part of image not loss quality.
+- **Crop**: Crop masking area from the original image to do inpainting, and paste the result back.
+Mainly for performance and memory reasons on high resolution image. This strategy may give better results for ldm model.

 ## Model Comparison
 
-Diffusion model(ldm) is **MUCH MORE** slower than GANs(lama)(1080x720 image takes 8s on 3090), but it's possible to get better
-result, see below example:
+| Model | Pron                                                                                                                                    | Corn                                                                                           |

+| LDM   | - It's possible to get better and more detail result, see example below<br/> - The balance of time and quality can be achieved by steps | - Slower than GAN model<br/> - Need more GPU memory<br/> - Not good for high resolution images |
