 You can restart your local server all you want, ```lt``` is smart enough to detect this and reconnect once it is back.
 
+### arguments
+
+Below are some common arguments. See `lt --help` for additional arguments
+
+* `--subdomain` request a named subdomain on the localtunnel server (default is random characters)
+* `--local-host` proxy to a hostname other than localhost
+
 ## API ##
 
 The localtunnel client is also usable through an API (for test integration, automation, etc)
 
+### localtunnel(port [,opts], fn)
+
+Creates a new localtunnel to the specified local `port`. `fn` will be called once you have been assigned a public localtunnel url. `opts` can be used to request a specific `subdomain`.
+
 ```javascript
 var localtunnel = require('localtunnel');
 
-var client = localtunnel.connect({
+var tunnel = localtunnel(port, function(err, tunnel) {
-    // the localtunnel server
+    if (err) ...
-    host: 'http://localtunnel.me',
+
-    // your local application port
+    // the assigned public url for your tunnel
-    port: 12345
+    // i.e. https://abcdefgjhij.localtunnel.me
+    tunnel.url;
 });
 
-// when your are assigned a url
+tunnel.on('close', function() {
-client.on('url', function(url) {
+    // tunnels are closed
-    // you can now make http requests to the url
-    // they will be proxied to your local server on port [12345]
-});
-
-client.on('error', function(err) {
-    // uh oh!
 });
 ```
 
+### opts
+
+* `subdomain` A *string* value requesting a specific subdomain on the proxy server. **Note** You may not actually receive this name depending on availablily.
+* `local_host` Proxy to this hostname instead of `localhost`. This will also cause the `Host` header to be re-written to this value in proxied requests.
+
+### Tunnel
+
+The `tunnel` instance returned to your callback emits the following events
+
+|event|args|description|
+|----|----|----|
+|error|err|fires when an error happens on the tunnel|
+|close||fires when the tunnel has closed|
