 # Web Stable Diffusion
 
-This project brings stable diffusion models to web browsers. **Everything runs inside the browser with no server support.** To our knowledge, this is the the world’s first stable diffusion completely running on the browser. Please check out our [GitHub repo](https://github.com/mlc-ai/web-stable-diffusion) to see how we did it. There is also a [demo](#text-to-image-generation-demo) which you can try out.
