+### Serializing a document
+
+```js
+var jsdom = require("jsdom").jsdom;
+var serializeDocument = require("jsdom").serializeDocument;
+
+var doc = jsdom("<!DOCTYPE html>hello");
+
+serializeDocument(doc) === "<!DOCTYPE html><html><head></head><body>hello</body></html>";
+doc.documentElement.outerHTML === "<html><head></head><body>hello</body></html>";
+```

 ## What Standards Does jsdom Support, Exactly?
 
 Our mission is to get something very close to a headless browser, with emphasis more on the DOM/HTML side of things than the CSS side. As such, our primary goals are supporting [The DOM Standard](http://dom.spec.whatwg.org/) and [The HTML Standard](http://www.whatwg.org/specs/web-apps/current-work/multipage/). We only support some subset of these so far; in particular we have the subset covered by the outdated DOM 2 spec family down pretty well. We're slowly including more and more from the modern DOM and HTML specs, including some `Node` APIs, `querySelector(All)`, attribute semantics, the history and URL APIs, and the HTML parsing algorithm.
