+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).

 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.

 ## Support

-Lo-Dash has been tested in at least Chrome 5-19, Firefox 1.5-12, IE 6-9, Opera 9.25-11.64, Safari 3.0.4-5.1.3, Node.js 0.4.8-0.6.18, Narwhal 0.3.2, RingoJS 0.8, and Rhino 1.7RC3.

 ## Custom builds

 Custom builds make it easy to create lightweight versions of Lo-Dash containing only the methods you need.
 We handle all the method dependency and alias mapping for you.

-Custom builds may be created in two ways:
+Mobile builds, with IE bug fixes and method compilation removed, may be created by using the `mobile` argument.

- 1. Use the`include` argument to pass the names of the methods to include in the build.
 ~~~ bash
-node build include=each,filter,map,noConflict
-node build include="each, filter, map, noConflict"
+node build mobile
 ~~~

- 2. Use the `exclude` argument to pass the names of the methods to exclude from the build.
+Custom builds may be created in three ways:
+
+ 1. Use the `category` argument to pass the categories of methods to include in the build.<br>
+    Valid categories are *"arrays"*, *"chaining"*, *"collections"*, *"functions"*, *"objects"*, and *"utilities"*.
 ~~~ bash
-node build exclude=isNaN,isUndefined,union,zip
-node build exclude="isNaN, isUndefined, union, zip"
+node build category=collections,functions
+node build category="collections, functions"
+node build mobile category=collections,functions
+~~~
+
+ 2. Use the `include` argument to pass the names of the methods to include in the build.
+~~~ bash
+node build include=each,filter,map
+node build include="each, filter, map"
+node build mobile include=each,filter,map
+~~~
+
+ 3. Use the `exclude` argument to pass the names of the methods to exclude from the build.
+~~~ bash
+node build exclude=union,uniq,zip
+node build exclude="union, uniq, zip"
+node build mobile exclude=union,uniq,zip
 ~~~

 Custom builds are saved to `lodash.custom.js` and `lodash.custom.min.js`.
