   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
+
+  Or, 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.)
+
   Compile a script:
   coffee /path/to/script.coffee
-  
+
   For documentation, usage, and examples, see:

+  or on webchat.freenode.net.
+
   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="pilwrap">                 <a class="pilcrow" href="#section-2">&#182;</a>               </div>               <p>The only dependency is on the <strong>Jison.Parser</strong>.</p>             </td>             <td class="code">               <div class="highlight"><pre><span class="p">{</span><span class="nx">Parser</span><span class="p">}</span> <span class="o">=</span> <span class="nx">require</span> <span class="s1">&#39;jison&#39;</span></pre></div>             </td>           </tr>                               <tr id="section-3">             <td class="docs">               <div class="pilwrap">                 <a class="pilcrow" href="#section-3">&#182;</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="pilwrap">                 <a class="pilcrow" href="#section-4">&#182;</a>               </div>               <p>Since we're going to be wrapped in a function by Jison in any case, if our

+a series of passes over the token stream, using this <strong>Rewriter</strong> to convert
+shorthand into the unambiguous long form, add implicit indentation and

+a time. This could certainly be changed into a single pass through the
+stream, with a big ol' efficient switch, but it's much nicer to work with
+like this. The order of these passes matters -- indentation must be
+corrected before implicit parentheses can be wrapped around blocks of code.</p>             </td>             <td class="code">               <div class="highlight"><pre>  <span class="nx">rewrite</span><span class="o">:</span> <span class="p">(</span><span class="nx">@tokens</span><span class="p">)</span> <span class="o">-&gt;</span>
