+## Setup instruction
+
+This app requires you to have the AUTOMATIC1111 WebUI that is running in server mode.
+
+You can have it running either on your own hardware with modern GPU from Nvidia or AMD, or running it using Google Colab. 
+
+1. Follow the setup instructions on [Stable-Diffusion-WebUI](https://github.com/AUTOMATIC1111/stable-diffusion-webui) repository.
+2. Add the arguments `--api --listen` to the command line arguments of WebUI launch script.
+3. After running the server, get the IP address, or URL of your WebUI server.
+4. On the first launch, app will ask you for the server URL, enter it and press Connect button. If you want to change the server URL, go to Settings tab, choose Configure option, and repeat the setup flow.
+
+If for some reason you have no ability to run your server instance, you can toggle the **Demo mode** swith on server setup page: it will allow you to test the app and get familiar with it, but it will return some mock images instead of AI-generated ones.
