 Ergo looks for a `.ergo` file inside the current directory. It must contain the names and URL of the services following the same format as `/etc/hosts` (`domain`+`space`+`url`). The main difference is it also considers the specified port.
 
-### Simplest Setup
+### Subdomains to http://localhost
+
+Run `ergo local` it'll attempt to bind to `localhost:80` and listen for requests to your services as "subdmains" eg. `http://serviceone.localhost` and `http://servicetwo.localhost`. (Check [examples](https://github.com/cristianoliveira/ergo/tree/master/examples) for more)
+
+**Note:** It __may__ requires sudo to bind to port 80.
+
+You can give it a different port by `ergo local -p <port>` and access it through `http://serviceone.localhost:<port>`.
+
+You can also add a different loopback in `/etc/hosts` like `echo '127.0.0.1 localapp' >> /etc/hosts` and run `ergo local -domain localapp` to access your services through `http://serviceone.localapp` and `http://servicetwo.localapp`.
+
+### Setting up as a webproxy
 
 **You need to set the `http://127.0.0.1:2000/proxy.pac` configuration on your system network config.**

 Simple :)

+### Using localhost loopback
+
+If you want to use subdomains with localhost loopback run the following commands:
+
+```bash
+# It requires sudo to bind to port 80
+sudo ergo local
+```
