 # stable-diffusion-webui-api
 
-This repo shows how to use stable-diffusion-webui to build Amazon SageMaker Docker image for inference and training job and how to generate images based on the combination with Stable-diffusion models and ControlNet / Lora models.
+## Overview
 
-You will find 2 Jupyter Notebooks: 1 for sync ControlNet / Lora inference, and 1 for async ControlNet / Lora inference.
+In this notebook, we explore how to build generative fill application and host Stable Diffusion/ ControlNet / segment anything models on SageMaker asynchronous endpoint using BYOC (Bring-your-own-container).
