   CoffeeScript is a little language that compiles into JavaScript.
   
-  Install the compiler:
-  gem install coffee-script
+  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:

   The source repository:
   git://github.com/jashkenas/coffee-script.git
   
-  To build CoffeeScript from source, install the "racc" gem and
-  run "rake build:parser". Then bin/coffee will work.

+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

+
+<ol>
+<li>Check that all paired tokens are balanced and in order.</li>
+<li>Rewrite the stream with a stack: if you see an <code>EXPRESSION_START</code>, add it
+to the stack. If you see an <code>EXPRESSION_END</code>, pop the stack and replace
+it with the inverse of what we've just popped.</li>
+<li>Keep track of "debt" for tokens that we manufacture, to make sure we end
+up balanced in the end.</li>
+<li>Be careful not to alter array or parentheses delimiters with overzealous
+rewriting.</li>

-This folder includes rough cuts of CoffeeScript syntax highlighters for 
-TextMate and Vim. Improvements to their lexing ability are always welcome.
+EXTRAS:
 
-To install the TextMate bundle, run `bin/coffee --install-bundle`, or drop it
-into "~/Library/Application Support/TextMate/Bundles".
+"extras/coffee-script.js" is a concatenated and compressed version of the 
+CoffeeScript compiler. To use it in the browser, include the script after any 
+inline script tags of type "text/coffeescript" on the page. It will compile
+and evaluate all of the scripts in order.
 
-To install the Vim highlighter, copy "coffee.vim" into the "syntax" directory of
-your vim72, and enable it in either of the following two ways:
-
-  * Manually, by running `:set syntax=coffee`
-  
-  * Or automatically, by creating a "filetype.vim" file within "~/.vim", which
-    contains something along these lines:
-    
-    if exists("did_load_filetypes")
-      finish
-    end
-    augroup filetypedetect
-      au! BufRead,BufNewFile *.coffee setfiletype coffee
