-A drop-in replacement for Underscore.js, from the devs behind [jsPerf.com](http://jsperf.com), that delivers [performance improvements](http://lodash.com/benchmarks), [bug fixes](https://github.com/bestiejs/lodash#closed-underscorejs-issues), and [additional features](https://github.com/bestiejs/lodash#features).
+A drop-in replacement<sup>[*](https://github.com/bestiejs/lodash/wiki/Drop-in-Disclaimer)</sup> for Underscore.js, from the devs behind [jsPerf.com](http://jsperf.com), that delivers [performance improvements](http://lodash.com/benchmarks), [bug fixes](https://github.com/bestiejs/lodash#closed-underscorejs-issues), and [additional features](https://github.com/bestiejs/lodash#features).

 Lo-Dash’s performance is gained by avoiding slower native methods, instead opting for simplified non-ES5 compliant methods optimized for common usage, and by leveraging function compilation to reduce the number of overall function calls.

+# Platform.js <sup>v1.0.0-pre</sup>
+
+A platform detection library that works on nearly all JavaScript platforms<sup><a name="fnref1" href="#fn1">1</a></sup>.
+
+## Disclaimer
+
+Platform.js is for informational purposes only and **not** intended as a substitution for [feature detection/inference](http://allyoucanleet.com/post/18087210413/feature-testing-costs#screencast2) checks.
+
+## BestieJS
+
+Platform.js is part of the BestieJS *"Best in Class"* module collection. This means we promote solid browser/environment support, ES5 precedents, unit testing, and plenty of documentation.
+
+## Documentation
+
+The documentation for Platform.js can be viewed here: [/doc/README.md](https://github.com/bestiejs/platform.js/blob/master/doc/README.md#readme)
+
+For a list of upcoming features, check out our [roadmap](https://github.com/bestiejs/platform.js/wiki/Roadmap).
+
+## Installation and usage
+
+In a browser or Adobe AIR:
+
+~~~ html
+<script src="platform.js"></script>
+~~~
+
+Via [npm](http://npmjs.org/):
+
+~~~ bash
+npm install platform
+~~~
+
+In [Narwhal](http://narwhaljs.org/), [Node.js](http://nodejs.org/), and [RingoJS](http://ringojs.org/):
+
+~~~ js
+var platform = require('platform');
+~~~
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+~~~ js
+load('platform.js');
+~~~
+
+In an AMD loader like [RequireJS](http://requirejs.org/):
+
+~~~ js
+require({
+  'paths': {
+    'platform': 'path/to/platform'
+  }
+},
+['platform'], function(platform) {
+  console.log(platform.name);
+});
+~~~
+
+Usage example:
+
+~~~ js
+// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
+platform.name; // 'IE'
+platform.version; // '10.0'
+platform.layout; // 'Trident'
+platform.os; // 'Windows Server 2008 R2 / 7 x64'
+platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'
+
+// or on an iPad
+platform.name; // 'Safari'
+platform.version; // '5.1'
+platform.product; // 'iPad'
+platform.manufacturer; // 'Apple'
+platform.layout; // 'WebKit'
+platform.os; // 'iOS 5.0'
+platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'
+
+// or parsing a given UA string
+var info = platform.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0) Gecko/20100101 Firefox/4.0 Opera 11.52');
+info.name; // 'Opera'
+info.version; // '11.52'
+info.layout; // 'Presto'
+info.os; // 'Mac OS X 10.7.2'
+info.description; // 'Opera 11.52 (identifying as Firefox 4.0) on Mac OS X 10.7.2'
+~~~
+
+## Footnotes
+
+  1. Platform.js has been tested in at least Adobe AIR 2.6, Chrome 5-15, Firefox 1.5-8, IE 6-10, Opera 9.25-11.52, Safari 2-5.1.1, Node.js 0.4.8-0.6.1, Narwhal 0.3.2, RingoJS 0.7-0.8, and Rhino 1.7RC3.
