+#object-keys <sup>[![Version Badge][2]][1]</sup>
+
+[![Build Status][3]][4] [![dependency status][5]][6]
+
+[![browser support][7]][8]
+
+An Object.keys shim. Uses Object.keys if available.
+
+## Example
+
+```js
+var keys = require('object-keys');
+var assert = require('assert');
+var obj = {
+	a: true,
+	b: true,
+	c: true
+};
+
+assert.equal(keys(obj), ['a', 'b', 'c']);
+```
+
+## Source
+Implementation taken directly from [es5-shim]([9]), with modifications, including from [lodash]([10]).
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`
