+__Sorting directed acyclic graphs, for Node.js, io.js and the browser__
+_This was originally done by Marcel Klehr. [Why not checkout his original repo?](https://github.com/marcelklehr/toposort)_
+
+## Installation
+There are a few ways for installing Toposort. Here are them:
+
+* Via NPM: `npm install toposort-class`
+* Via Bower: `bower install toposort`
+* Via Git: `git clone git://github.com/gustavohenke/toposort.git`
+* [Direct download](https://raw.githubusercontent.com/gustavohenke/toposort/master/build/toposort.js) ([Minified](https://raw.githubusercontent.com/gustavohenke/toposort/master/build/toposort.min.js)) for use in the browser
+
+## Example
+Let's say you have the following dependency graph:
+
+* Plugin depends on Backbone and jQuery UI Button;
+* Backbone depends on jQuery and Underscore;
+* jQuery UI Button depends on jQuery UI Core and jQuery UI Widget;
+* jQuery UI Widget and jQuery UI Core depend on jQuery;
+* jQuery and Underscore don't depend on anyone.
+
+Now, how would you sort this in a way that each asset will be correctly placed? You'll probably need the following sorting:
+
+* `jQuery`, `jQuery UI Core`, `jQuery UI Widget`, `jQuery UI Button`, `Underscore`, `Backbone`, `Plugin`
+
+You can achieve it with the following code, using `toposort-class`:
+```javascript
+var Toposort = require('toposort-class'),
+	t = new Toposort();
+
+t.add("jquery-ui-core", "jquery")
+ .add("jquery-ui-widget", "jquery")
+ .add("jquery-ui-button", ["jquery-ui-core", "jquery-ui-widget"])
+ .add("plugin", ["backbone", "jquery-ui-button"])
+ .add("backbone", ["underscore", "jquery"]);
+
+console.log(t.sort().reverse());
+
+/* Will output:
+ * ['jquery', 'jquery-ui-core', 'jquery-ui-widget', 'jquery-ui-button', 'underscore', 'backbone', 'plugin']
+ *
+ * And you're done.
+ */
+```
+
+## Usage
+CommonJS (Node.js and io.js):
+```javascript
+var Toposort = require('toposort-class'),
+	t = new Toposort();
+```
+
+Browser with AMD:
+```javascript
+define("myModule", ["Toposort"], function(Toposort) {
+    var t = new Toposort();
+});
+```
+
+Browser without AMD:
+```javascript
+var t = new window.Toposort();
+```
+
+or whatever global object there is instead of `window`.
+
+## API
+
+#### `.add(item, deps)`
+* _{String}_ `item` - The name of the dependent item that is being added
+* _{Array|String}_ `deps` - A dependency or list of dependencies of `item`
+
+__Returns:__ _{Toposort}_ The Toposort instance, for chaining.
+
+#### `.sort()`
+__Returns:__ _{Array}_ The list of dependencies topologically sorted.
+
+This method will check for cyclic dependencies, like "A is dependent of A".
+
+#### `.clear()`
+__Returns:__ _{Toposort}_ The Toposort instance, for chaining.
+
+Clears all edges, effectively resetting the instance.
+
+#### `.Toposort`
+
+Reference to the Toposort constructor.
