+# Toposort
+
+Sort directed acyclic graphs
+
+[![Build Status](https://travis-ci.org/marcelklehr/toposort.png)](https://travis-ci.org/marcelklehr/toposort)
+
+## Installation
+
+`npm install toposort` or `component install marcelklehr/toposort`  
+
+then in your code:
+
+```js
+toposort = require('toposort')
+```
+
+## Usage
+We want to sort the following graph.
+
+![graph](https://cdn.rawgit.com/marcelklehr/toposort/8b14e9fd/graph.svg)
+
+```js
+// First, we define our edges.
+var graph = [
+  ['put on your shoes', 'tie your shoes']
+, ['put on your shirt', 'put on your jacket']
+, ['put on your shorts', 'put on your jacket']
+, ['put on your shorts', 'put on your shoes']
+]
+
+
+// Now, sort the vertices topologically, to reveal a legal execution order.
+toposort(graph)
+// [ 'put on your shirt'
+// , 'put on your shorts'
+// , 'put on your jacket'
+// , 'put on your shoes'
+// , 'tie your shoes' ]
+```
+
+(Note that there is no defined order for graph parts that are not connected
+ -- you could also put on your jacket after having tied your shoes...)
+
+### Sorting dependencies
+It is usually more convenient to specify *dependencies* instead of "sequences".
+```js
+// This time, edges represent dependencies.
+var graph = [
+  ['tie your shoes', 'put on your shoes']
+, ['put on your jacket', 'put on your shirt']
+, ['put on your shoes', 'put on your shorts']
+, ['put on your jacket', 'put on your shorts']
+]
+
+toposort(graph) 
+// [ 'tie your shoes'
+// , 'put on your shoes'
+// , 'put on your jacket'
+// , 'put on your shirt'
+// , 'put on your shorts' ]
+
+// Now, reversing the list will reveal a legal execution order.
+toposort(graph).reverse() 
+// [ 'put on your shorts'
+// , 'put on your shirt'
+// , 'put on your jacket'
+// , 'put on your shoes'
+// , 'tie your shoes' ]
+```
+
+## API
+
+### toposort(edges)
+
++ edges {Array} An array of directed edges describing a graph. An edge looks like this: `[node1, node2]` (vertices needn't be strings but can be of any type).
+
+Returns: {Array} a list of vertices, sorted from "start" to "end"
+
+Throws an error if there are any cycles in the graph.
+
+### toposort.array(nodes, edges)
+
++ nodes {Array} An array of nodes
++ edges {Array} An array of directed edges. You don't need to mention all `nodes` here.
+
+This is a convenience method that allows you to define nodes that may or may not be connected to any other nodes. The ordering of unconnected nodes is not defined.
+
+Returns: {Array} a list of vertices, sorted from "start" to "end"
+
+Throws an error if there are any cycles in the graph.
+
+## Tests
+
+Run the tests with `node test.js`.
