+### `app.setAsDefaultProtocolClient(protocol)` _OS X_ _Windows_
+
+ * `protocol` String - The name of your protocol, without `://`. If you want your
+   app to handle `electron://` links, call this method with `electron` as the
+   parameter.
+   
+This method sets the current executable as the default handler for a protocol
+(aka URI scheme). It allows you to integrate your app deeper into the operating
+system. Once registered, all links with `your-protocol://` will be openend with
+the current executable. The whole link, including protocol, will be passed to
+your application as a parameter.
+ 
+**Note:** On OS X, you can only register protocols that have been added to
+your app's `info.plist`, which can not be modified at runtime. You can however
+change the file with a simple text editor or script during build time.
+Please refer to [Apple's documentation][CFBundleURLTypes] for details.
+
+The API uses the Windows Registry and LSSetDefaultHandlerForURLScheme internally.
