+### Deploy with your domain name
+You can deploy the server with your domain name by setting up a reverse proxy with Nginx.
+
+1. Install Nginx if you don't already have it.
+- Linux : https://nginx.org/en/docs/install.html
+- Windows : https://nginx.org/en/docs/windows.html
+
+2. Edit [`nginx.conf`](https://github.com/jhj0517/Whisper-WebUI/blob/master/backend/nginx/nginx.conf) for your domain name.
+https://github.com/jhj0517/Whisper-WebUI/blob/895cafe400944396ad8be5b1cc793b54fecc8bbe/backend/nginx/nginx.conf#L12
+
+3. Add an A type record of your public IPv4 address in your domain provider. (you can get it by searching "What is my IP" in Google)
+
+4. Open a terminal and go to the location of [`nginx.conf`](https://github.com/jhj0517/Whisper-WebUI/blob/master/backend/nginx/nginx.conf), then start the nginx server, so that you can manage nginx-related logs there.
+```shell
+cd backend/nginx
+nginx -c "/path/to/Whisper-WebUI/backend/nginx/nginx.conf"
+```
+
+5. Open another terminal in the root project location `/Whisper-WebUI`, and deploy the app with `uvicorn` or whatever. Now the app will be available at your domain.
+```shell
+uvicorn backend.main:app --host 0.0.0.0 --port 8000
+```
+
+6. When you turn off nginx, you can use `nginx -s stop`.
+```shell
+cd backend/nginx
+nginx -s stop -c "/path/to/Whisper-WebUI/backend/nginx/nginx.conf"
+```
+
+
 ## Configuration
 You can set some server configurations in [config.yaml](https://github.com/jhj0517/Whisper-WebUI/blob/master/backend/configs/config.yaml). 
 <br>For example, initial model size for Whisper or the cleanup frequency and TTL for cached files.
