+## 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:
-  sudo bin/cake install
-  
-  Compile a script:
-  coffee /path/to/script.coffee
-  
-  For documentation, usage, and examples, see:

+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 external scopes.</p>

-from this grammar file. Jison is a bottom-up parser generator, similar in
-style to <a href="http://www.gnu.org/software/bison">Bison</a>, implemented in JavaScript.
-It can recognize <a href="http://en.wikipedia.org/wiki/LR_grammar">LALR(1), LR(0), SLR(1), and LR(1)</a>
-type grammars. To create the Jison parser, we list the pattern to match
-on the left-hand side, and the action to take (usually the creation of syntax
-tree nodes) on the right. As the parser runs, it
-shifts tokens from our token stream, from left to right, and
-<a href="http://en.wikipedia.org/wiki/Bottom-up_parsing">attempts to match</a>
-the token sequence against the rules below. When a match can be made, it
-reduces into the <a href="http://en.wikipedia.org/wiki/Terminal_and_nonterminal_symbols">nonterminal</a>
-(the enclosing name at the top), and we proceed from there.</p>
-
-<p>If you run the <code>cake build:parser</code> command, Jison constructs a parse table
-from our rules and saves it into <code>lib/parser.js</code>.</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>The only dependency is on the <strong>Jison.Parser</strong>.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="nv">Parser: </span><span class="nx">require</span><span class="p">(</span><span class="s1">&#39;jison&#39;</span><span class="p">).</span><span class="nx">Parser</span></pre></div>             </td>           </tr>                               <tr id="section-3">             <td class="docs">               <div class="octowrap">                 <a class="octothorpe" href="#section-3">#</a>               </div>               <h2>Jison DSL</h2>             </td>             <td class="code">               <div class="highlight"><pre></pre></div>             </td>           </tr>                               <tr id="section-4">             <td class="docs">               <div class="octowrap">                 <a class="octothorpe" href="#section-4">#</a>               </div>               <p>Since we're going to be wrapped in a function by Jison in any case, if our

-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
