-## Retrieving proxy URL
+## Retrieving proxy URL and parsed config
 
 As the module does some extra job determining the proxy (including parsing the environment variables) and does some normalization (like defaulting the protocol to `http:`) it may be useful to retrieve the proxy URL used by the module.
 
 The property `globalTunnel.proxyUrl` is the URL-formatted (including the optional basic auth if provided) proxy config currently in use. It is `null` if the proxy is not currently enabled.
 
+Similarly, the `globalTunnel.proxyConfig` contains the entire parsed and normalized config.
