-A drop-in replacement for [Underscore.js](https://github.com/documentcloud/underscore/) that delivers up to [8x performance improvements](http://jsperf.com/lodash-underscore#chart=bar), [bug fixes](https://github.com/bestiejs/lodash/blob/master/test/test.js#L71), and additional features.
+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).
 
-## BestieJS
+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.
 
-Lo-Dash 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.
+## Download
 
-## Documentation
+ * [Development source](https://raw.github.com/bestiejs/lodash/v0.3.0/lodash.js)
+ * [Production source](https://raw.github.com/bestiejs/lodash/v0.3.0/lodash.min.js)
+ * For optimal performance, [create a custom build](https://github.com/bestiejs/lodash#custom-builds) with only the features you need
 
-The documentation for Lo-Dash can be viewed here: [/doc/README.md](https://github.com/bestiejs/lodash/blob/master/doc/README.md#readme)
+## Dive in
 
-Underscore's [documentation](http://documentcloud.github.com/underscore/) may also be used.
+We’ve got [API docs](http://lodash.com/docs), [benchmarks](http://lodash.com/benchmarks), and [unit tests](http://lodash.com/tests).
 
 For a list of upcoming features, check out our [roadmap](https://github.com/bestiejs/lodash/wiki/Roadmap).

-## What else?
+ * [Introducing Lo-Dash](http://dl.dropbox.com/u/513327/allyoucanleet/post/20/file/screencast.mp4)
+ * [Optimizations and custom builds](http://dl.dropbox.com/u/513327/allyoucanleet/post/21/file/screencast.mp4)
 
-Lo-Dash comes with AMD loader support baked in, chainable `_.each`, and will [soon address](https://github.com/bestiejs/lodash/wiki/Roadmap) cross-browser object iteration issues.
+## Features
 
-## Screencast
+ * AMD loader support (RequireJS, curl.js, etc.)
+ * [_.bind](http://lodash.com/docs#bind) supports *"lazy"* binding
+ * [_.debounce](http://lodash.com/docs#debounce)’ed functions match [_.throttle](http://lodash.com/docs#throttle)’ed functions’ return value behavior
+ * [_.forEach](http://lodash.com/docs#forEach) is chainable
+ * [_.forIn](http://lodash.com/docs#forIn) for iterating over an object’s own and inherited properties
+ * [_.forOwn](http://lodash.com/docs#forOwn) for iterating over an object’s own properties
+ * [_.groupBy](http://lodash.com/docs#groupBy), [_.sortedIndex](http://lodash.com/docs#sortedIndex), and [_.uniq](http://lodash.com/docs#uniq) accept a `thisArg` argument
+ * [_.indexOf](http://lodash.com/docs#indexOf) and [_.lastIndexOf](http://lodash.com/docs#lastIndexOf) accept a `fromIndex` argument
+ * [_.partial](http://lodash.com/docs#partial) for more functional fun
+ * [_.size](http://lodash.com/docs#size) supports returning the `length` of string values
+ * [_.template](http://lodash.com/docs#template) utilizes [sourceURLs](http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/#toc-sourceurl) for easier debugging
 
-For more information check out [this screencast](http://dl.dropbox.com/u/513327/allyoucanleet/post/20/file/screencast.mp4) over Lo-Dash.
+## Support
+
+Lo-Dash has been tested in at least Chrome 5-19, Firefox 1.5-13, 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.
+
+Mobile builds, with IE bug fixes and method compilation removed, may be created by using the `mobile` argument.
+
+~~~ bash
+node build mobile
+~~~
+
+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 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`.
