+# SimpleMDE Editor & Markdown for SilverStripe 3
+This module adds a field and a data type that allows for Markdown editing in the CMS, and HTML template rendering
+using the Github Flavoured Markdown parser [Parsedown](http://parsedown.org/).
+
+It is integrated with the [SimpleMDE Markdown Editor](https://github.com/NextStepWebs/simplemde-markdown-editor)
+for CMS editing (see "Editor limitations" below).
+
+## Requirements
+- SilverStripe 3.x
+
+## Usage
+Use the Markdown data type as your fields data type, then use the SimpleMDEEditor field in the CMS for editing.
+
+### Page class:
+
+```php
+class MyMarkdownPage extends Page
+{
+    public static $db=array(
+        'MarkdownContent'=>'Markdown'
+    );
+
+    public function getCMSFields()
+    {
+        $fields=parent::getCMSFields();
+
+        $editor = SimpleMDEEditor::create('MarkdownContent', 'Page Content (Markdown)');
+        $fields->addFieldToTab('Root.Main', $editor);
+
+        return $fields;
+    }
+}
+```
+
+### Template:
+
+```html
+<div class="content">
+    $MarkdownContent  <!-- Will show as rendered html -->
+</div>
+```
+
+## Editor limitations:
+SimpleMDE has some nice features such as full-page editing/preview, as well as "Side by Side" editing
+[see demo](http://nextstepwebs.github.io/simplemde-markdown-editor/). Unfortunately this doesn't play nice with
+SilverStripe's CMS as the fullscreen elements are positioned statically. Rather than some ugly hacking, and until
+someone hopefully finds an elegant solution (pull requests please), fullscreen & side-by-side functionality has been
+hidden from the toolbar.
