-# stable-diffusion-webui
-Stable Diffusion web UI
+# Stable Diffusion web UI
+A browser interface based on Gradio library for Stable Diffusion.
+
+Original script with Gradio UI was written by a kind anonymopus user. This is a modification.
+
+![](screenshot.png)
+
+## Stable Diffusion
+
+This script assumes that you already have main Stable Diffusion sutff installed, assumed to be in directory `/sd`.
+If you don't have it installed, follow the guide:
+
+- https://rentry.org/kretard
+
+This repository's `webgui.py` is a replacement for `kdiff.py` from the guide.
+
+Particularly, following files must exist:
+
+- `/sd/configs/stable-diffusion/v1-inference.yaml`
+- `/sd/models/ldm/stable-diffusion-v1/model.ckpt`
+- `/sd/ldm/util.py`
+- `/sd/k_diffusion/__init__.py`
+
+## GFPGAN
+
+If you want to use GFPGAN to improve generated faces, you need to install it separately.
+Follow instructions from https://github.com/TencentARC/GFPGAN, but when cloning it, do so into Stable Diffusion main directory, `/sd`.
+After that download [GFPGANv1.3.pth](https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.3.pth) and put it
+into the `/sd/GFPGAN/experiments/pretrained_models` directory. If you're getting troubles with GFPGAN support, follow instructions
+from the GFPGAN's repository until `inference_gfpgan.py` script works.
+
+The following files must exist:
+
+- `/sd/GFPGAN/inference_gfpgan.py`
+- `/sd/GFPGAN/experiments/pretrained_models/GFPGANv1.3.pth`
+
+If the GFPGAN directory does not exist, you will not get the option to use GFPGAN in the UI. If it does exist, you will either be able
+to use it, or there will be a message in console with an error related to GFPGAN.
+
+## Web UI
+
+Run the script as:
+
+`python webui.py`
+
+When running the script, you must be in the main Stable Diffusion directory, `/sd`. If you cloned this repository into a subdirectory 
+of `/sd`, say, the `stable-diffusion-webui` directory, you will run it as:
+
+`python stable-diffusion-webui/webui.py`
+
+When launching, you may get a very long warning message related to some weights not being used. You may freely ignore it.
+After a while, you will get a message like this:
+
+```
+Running on local URL:  http://127.0.0.1:7860/
+```
+
+Open the URL in browser, and you are good to go.
