+## executr
+
+Let your users execute and play with the CoffeeScript and JavaScript in your documentation
+
+### Example
+
+See our messenger documentation for an example: http://hubspot.github.com/messenger/
+
+### Including
+
+````html
+<!-- You should already have jQuery included -->
+
+<!-- Code Mirror is used to make the code blocks editable -->
+<script type="text/javascript" src="lib/CodeMirror/codemirror.js"></script>
+
+<!-- Include the CodeMirror languages you're going to use -->
+<script type="text/javascript" src="lib/CodeMirror/mode/coffeescript/coffeescript.js"></script>
+<script type="text/javascript" src="lib/coffee-script.js"></script>
+
+<script type="text/javascript" src="build/js/executr.js"></script>
+
+<link rel="stylesheet" type="text/css" media="screen" href="lib/CodeMirror/codemirror.css">
+<link rel="stylesheet" type="text/css" media="screen" href="build/css/executr.css">
+````
+
+### Usage
+
+The code blocks you wish to be executable should be wrapped in `<code executable></code>`.
+
+Run `$.executr` on the container of multiple code elements, the body, or a single code block.
+
+The blocks will be converted into CodeMirror Editors, and a run button will be added.  If you're not interested
+in the code being editable, take a look at the v1.1 tag.
+
+Only the text (not tags) in the block will be executed, feel free to wrap your already-syntax-highlighted code.
+
+The code editor will assume the height + 10px and width of the code element.
+
+````html
+<pre><code executable>
+$ ->
+  alert "Testing!"
+</code></pre>
+````
+
+````javascript
+$(function(){
+  $('body').executr();
+});
+````
+
+You can also make javascript executable, by either adding a `data-type="javascript"` attribute to the code
+block, or by adding `defaultType: 'javascript'` to the executr call.
+
+````html
+<code data-type="javascript" executable>
+alert("Testing!");
+</code>
+````
+
+### Other Options
+
+$.executr can be passed the following options
+
+````coffeescript
+{
+    codeSelector: 'code[executable]' # The jQuery selector items to be bound must match
+
+    outputTo: 'div.output' # An element which should receive the output.
+    appendOutput: true # Whether output should replace the contents of outputTo, or append to it
+
+    defaultType: 'coffeescript' # The default source languange, if not supplied as a data-type attribute
+    type: 'coffeescript' # The type to force on all code blocks, even if otherwise specified.  Can also be a function.
+    coffeeOptions: {} # Extra options for the CoffeeScript compiler
+
+    codeMirrorOptions: {} # Extra options for CodeMirror
+
+    setUp: -> # Code to run before each code block
+    tearDown: -> # Code to run after each code block
+}
+````
+
+#### Events
+
+Executr will fire two events on the element it is bound to:
+
+- `executrBeforeExecute(code string, normalized code language, executr options)`
+- `executrAfterExecute(code output, code string, normalized code language, executr options)`
+
+#### Contributing
+
+You can build the project by running `./build.sh`.  It requires the CoffeeScript compiler.
