+## How to contribute to CoffeeScript
+
+* Before you open a ticket or send a pull request, [search](https://github.com/jashkenas/coffeescript/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/coffeescript/tree/master/test).
+
+* Use the same coding style as the rest of the [codebase](https://github.com/jashkenas/coffeescript/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.

   CoffeeScript is a little language that compiles into JavaScript.
-  
-  Install Node.js, and then the CoffeeScript compiler:
+
+  If you have the Node Package Manager installed:
+  npm install -g coffee-script
+  (Leave off the -g if you don't wish to install globally.)
+
+  Or, if you don't wish to use npm:
   sudo bin/cake install
-  
-  Compile a script:
+
+  Execute a script:
   coffee /path/to/script.coffee
-  
+
+  Compile a script:
+  coffee -c /path/to/script.coffee
+
   For documentation, usage, and examples, see:

+              <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="octowrap">                 <a class="octothorpe" href="#section-2">#</a>               </div>               <p>Set up exported variables for both <strong>Node.js</strong> and the browser.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="k">this</span><span class="p">.</span><span class="nv">exports: </span><span class="k">this</span> <span class="nx">unless</span> <span class="nx">process</span><span class="o">?</span>
