+```
 
 ## Usage
 
 ```js
-var og = require('open-graph');
+const og = require('open-graph');
 
-var url = "http://github.com/samholmes/node-open-graph/raw/master/test.html";
+const url = 'http://github.com/samholmes/node-open-graph/raw/master/test.html';
 
-og(url, function(err, meta){
-	console.log(meta);
-})
+og(url, function (err, meta) {
+  console.log(meta);
+});
 ```
 
 Outputs:
 
-	{
-	  title: 'OG Testing',
-	  type: 'website',
-	  url: 'http://github.com/samholmes/node-open-graph/raw/master/test.html',
-	  site_name: 'irrelavent',
-	  description: 'This is a test bed for Open Graph protocol.',
-	  image: 
-	  { 
-	   	 url: 'http://google.com/images/logo.gif',
-	     width: '100',
-	     height: '100'

+{
+  title: 'OG Testing',

 # Todo
 
-1. **Better parser**  
-	Meta data should be parsed into pure JSON and arrays should be handled at root nodes, not leaf nodes
-2. **Better data types**  
-	Convert properties to numbers, etc.
-3. **Fallback data**  
-	If Open Graph data isn't present, scrap img elements and document titles off the page.
