 # short_url
 This is a simple application to short you urls with your own web server.
 It is based on Nodejs and Redis.
-You will have to change the IPs in the `index.js` and `./public/index.html` files to your public IP or domain.
+You can change the public ports `8080` (web UI) and `8081` (websocket) in the `docker-compose.yml` file
-To start the server simply execute `index.js`:
+To start the server simply use `docker-compose`:
 ```
-screen -A -m -d -S short_url nodejs index.js
+docker-compose -p surl up -d
 ```
-It's recommended to use a reverse proxy like nginx to manage SSL certificates etc.
