+mezzanine-mdown
+===============
+
+This package provides widgets and filters for mezzanine that enable admins
+to use markdown formatting to create their site content, rather than using
+the tinymce editor to generate html.
+
 
 WMD is a rich text editor (*RTE*) that helps to produce markdown formatted text.
-This package provides the neccessary ``RICHTEXT_WIDGET_CLASS`` and 
-``RICHTEXT_FILTER`` to enable wmd and markdown for *rich* content types in 
-mezzanine such as pages and blog posts.
+This package provides widgets and filters to enable wmd and markdown for 
+*rich content* types in mezzanine, such as *pages* and *blog posts*.

+media with staticfiles or symlinks
+
+Template Overrides
+^^^^^^^^^^^^^^^^^^
+
+templates, add to installed apps 
+
+
+Configuration
+-------------
+
+``RICHTEXT_WIDGET_CLASS``
+^^^^^^^^^^^^^^^^^^^^^^^^^
+This package provides 2 options for this setting.
+
+``mdown.forms.WmdWidget``:
+     Activates the ``WMD`` rich text editor.
+
+``mdown.forms.PlainWidget``:
+     Use a plain Textarea (no rich text editor).
+
+
+``RICHTEXT_FILTER``
+^^^^^^^^^^^^^^^^^^^
+Again, there are 2 options for this setting.
+
+``mdown.filters.plain``:
+    Renders the content using *vanilla* markdown formatting.
+
+``mdown.filters.codehilite``:
+    Renders the content using markdown with the ``codehilite`` extension
+    enabled.

+WMD: The Wysiwym Markdown Editor
+================================
+
+Introduction
+------------
+
+This is the branch of wmd for [Open Library](http://openlibrary.org), forked from the [Stackoverflow branch of wmd](http://github.com/derobins/wmd).
+
+Major Changes
+-------------
+
+* Explicit function call is required to enable WMD editor for a textarea
+* Can work with multiple textareas in the same page
+* jquery plugin to simplify the usage
+
+How to use
+----------
+
+Example using jquery plugin:
+
+    <html>
+        <head>
+            <title>WMD Example using jquery</title>
+            <link rel="stylesheet" type="text/css" href="wmd.css"/>
+
+            <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
+            <script type="text/javascript" src="jquery.wmd.min.js"></script>
+        </head>
+        <body>
+            <h1>WMD Example using jquery</h1>
+            <div>
+                <textarea id="notes"/>
+            </div>
+    
+            <script type="text/javascript">
+                $().ready(function() {
+                   $("#notes").wmd(); 
+                });
+            </script>
+        </body>
+    </html>
+    
+Example without using jquery:
+
+    <html>
+        <head>
+            <title>WMD Example</title>
+            
+            <link rel="stylesheet" type="text/css" href="wmd.css"/>
+            
+            <script type="text/javascript" src="wmd.js"></script>
+            <script type="text/javascript" src="showdown.js"></script>
+        </head>
+        <body>
+            <h1>WMD Example</h1>

+            </div>
+    
+            <script type="text/javascript">

+
+//
+// Wherever possible, Showdown is a straight, line-by-line port
+// of the Perl version of Markdown.
+//
+// This is not a normal parser design; it's basically just a
+// series of string substitutions.  It's hard to read and
+// maintain this way,  but keeping Showdown close to the original
+// design makes it easier to port new features.
+//
+// More importantly, Showdown behaves like markdown.pl in most
+// edge cases.  So web applications can do client-side preview
+// in Javascript, and then build identical HTML on the server.
+//
+// This port needs the new RegExp functionality of ECMA 262,
+// 3rd Edition (i.e. Javascript 1.5).  Most modern web browsers
+// should do fine.  Even with the new regular expression features,
+// We do a lot of work to emulate Perl's regex functionality.
+// The tricky changes in this file mostly have the "attacklab:"
+// label.  Major or self-explanatory changes don't.
+//
+// Smart diff tools like Araxis Merge will be able to match up
+// this file with markdown.pl in a useful way.  A little tweaking
+// helps: in a copy of markdown.pl, replace "#" with "//" and
+// replace "$text" with "text".  Be sure to ignore whitespace
+// and line endings.
+//
+
+
+//
+// Showdown usage:
+//
+//   var text = "Markdown *rocks*.";
+//
+//   var converter = new Attacklab.showdown.converter();
+//   var html = converter.makeHtml(text);
+//
+//   alert(html);

+// file before uncommenting it.
