+## How to contribute to CoffeeScript
+
+* Before you open a ticket or send a pull request, [search](https://github.com/jashkenas/coffee-script/issues) for previous discussions about the same feature or issue. Add to the earlier ticket if you find one.
+
+* Before sending a pull request for a feature, be sure to have [tests](https://github.com/jashkenas/coffee-script/tree/master/test).
+
+* Use the same coding style as the rest of the [codebase](https://github.com/jashkenas/coffee-script/tree/master/src). If you're just getting started with CoffeeScript, there's a nice [style guide](https://github.com/polarmobile/coffeescript-style-guide).
+
+* In your pull request, do not add documentation to `index.html` or re-build the minified `coffee-script.js` file. We'll do those things before cutting a new release.

+              <p>The <strong>Scope</strong> class regulates lexical scoping within CoffeeScript. As you
 generate code, you create a tree of scopes in the same shape as the nested
 function bodies. Each scope knows about the variables declared within it,
 and has a reference to its parent enclosing scope. In this way, we know which
 variables are new and need to be declared with <code>var</code>, and which are shared
-with the outside.</p>             </td>             <td class="code">               <div class="highlight"><pre></pre></div>             </td>           </tr>                               <tr id="section-2">             <td class="docs">               <div class="pilwrap">                 <a class="pilcrow" href="#section-2">&#182;</a>               </div>               <p>Import the helpers we plan to use.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="p">{</span><span class="nx">extend</span><span class="p">,</span> <span class="nx">last</span><span class="p">}</span> <span class="o">=</span> <span class="nx">require</span> <span class="s1">&#39;./helpers&#39;</span>

+
+    <p>
+      Besides being used as an ordinary programming language, CoffeeScript may
+      also be written in "literate" mode. If you name your file with a
+      <tt>.litcoffee</tt> extension, you can write it as a Markdown document &mdash;
+      a document that also happens to be executable CoffeeScript code. The compiler
+      will treat any indented blocks (Markdown's way of indicating source code)
+      as code, and ignore the rest as comments.
+    </p>
+
+    <p>
+      Just for kicks, a little bit of the compiler is currently implemented in this fashion:
+      See it
+      <a href="https://gist.github.com/jashkenas/3fc3c1a8b1009c00d9df">as a document</a>,

+      and <a href="http://cl.ly/LxEu">properly highlighted in a text editor</a>.
+    </p>
+
+    <p>
+      I'm fairly excited about this direction for the language, and am looking

+        <li>
+          Named loop variables no longer have different scoping heuristics than

+          duplicate property names in object literals, duplicate parameters in

+        <li>
+          Conditional assignment of previously undefined variables
