 ## Usage
 
+Works out of the box in the browser:
+
 ```js
-var domify = require('domify')
+var domify = require('domify');
 
 document.addEventListener('DOMContentLoaded', function() {
-  var el = domify('<p>Hello <em>there</em></p>')
-  document.body.appendChild(el)
-})
+  var el = domify('<p>Hello <em>there</em></p>');
+  document.body.appendChild(el);
+});
+```
+
+You can also run it in *node* and *iojs*. Just pass a custom implementation of `document`:
+
+```js
+var jsdom = require('jsdom').jsdom();
+
+domify('<p>Hello <em>there</em></p>', jsdom.defaultView.document);
 ```
