 To change the port or the ip adress to listen for you can use `-p` and `-a` options respectivelly.
 
+There is alse the `-d` option that will set what domain name upfast will return when returning the file path when uploaded.

 > example
 
 ```bash
-./upfast -p 8080 -a 0.0.0.0
+./upfast -p 8080 -a 0.0.0.0 -d https://upfast.cronyakatsuki.xyz
 ```
 
 By default upfast listen's on 127.0.0.1 adress so if you wan't to access it outside your network you will either need to listen to 0.0.0.0 or use a reverse proxy. I recommend the usage of a reverse proxy.
