+============
+
+[Wicked Good XPath](https://github.com/google/wicked-good-xpath) is a fast implementation of [document.createExpression](https://developer.mozilla.org/en-US/docs/DOM/document.createExpression) and [document.evaluate](https://developer.mozilla.org/en-US/docs/DOM/document.evaluate) ([DOM3-XPath](http://www.w3.org/TR/2004/NOTE-DOM-Level-3-XPath-20040226/DOM3-XPath.html)) in pure Javascript.
+
+Version
+------
+
+`x.y.z`: `x.y` refers to the Wicked Good XPath revision when `wgxpath.install.js` was built; `z` refers to any improvements to this package.
+
+I'm pretty lazy, so I didn't build Wicked Good XPath myself. When the pre-compiled [wgxpath.install.js](https://github.com/google/wicked-good-xpath/releases/latest) is updated, I'll update this package.
+
+Installation
+------------
+
+Install with [npm](http://npmjs.org/):
+
+    npm install wgxpath
+
+Make sure things are working:
+
+    node node_modules/wgxpath/word_of_the_day.js
+
+Example
+-------
+
+This example scrapes the [Merriam-Webster Word of the Day](http://www.merriam-webster.com/word-of-the-day/). This code can also be found in `word_of_the_day.js`.
+
+```javascript
+var wgxpath = require('wgxpath');
+var jsdom = require('jsdom');
+
+var url = 'http://www.merriam-webster.com/word-of-the-day/';
+var expressionString = '//*[@id="content"]/div[3]/ul/li[1]/strong';
+
+jsdom.env({
+  html: url,
+  done: function(errors, window) {
+    wgxpath.install(window);
+    var expression = window.document.createExpression(expressionString);
+    var result = expression.evaluate(window.document,
+        wgxpath.XPathResultType.STRING_TYPE);
+    console.log('The Word of the Day is "' + result.stringValue + '."');
+  }
+});
+```
