 The following example will create a `WebView` and expose a function to it:
 
-	@import 'MochaJSWebScriptingObject.js'
+```javascript
+@import 'MochaJSWebScriptingObject.js'
 
-	//  Create a WebView
+//  Create a WebView
 
-	var webView = WebView.new();
+var webView = WebView.new();
 
-	//  Expose functions
+//  Expose functions

-		demo: function(){
-			var app = [NSApplication sharedApplication];
-			[app displayDialog:"This is being called from a WebView! Cool!" withTitle:"Alert"];

 How does it work?
 ----------------
 
-`MochaJSWebScriptingObject` leverages [Mocha's](https://github.com/logancollins/Mocha) methods for manipulating the Objective-C runtime. It creates an NSObject complying with the [`WebScripting`](https://developer.apple.com/library/mac/documentation/Cocoa/Reference/WebKit/Protocols/WebScripting_Protocol/index.html) protocol and manages function exposure between CocoaScript -> Objective-C -> WebView.
