+# Parser package
+
+## Installing
+
+Simply add `parser` to your config.php `always_loaded.packages` config option.
+
+## Included Parsers
+
+* Markdown - A PHP version of Markdown by Michel Fortin.
+
+## Usage
+
+```php
+// old usage still valid, will load app/views/example.php
+View::forge('example');
+
+// load a SimpleTags template, will load and parse app/views/example.stags
+View::forge('example.stags');
+
+// load a Mustache template, will load and parse app/views/example.mustache
+View::forge('example.mustache');
+
+// load a Twig template, will load and parse app/views/example.twig
+View::forge('example.twig');
+
+// load a Hybrid Haml / Twig template, ATTENTION: this one expects app/views/example.twig and {% haml %} code at the top of the view
+View::forge('example.mthaml');
+
+// load a Jade template, will load and parse app/views/example.jade
+View::forge('example.jade');
+
+// load a Haml template, will load and parse app/views/example.haml
+View::forge('example.haml');
+
+// load a Smarty template, will load and parse app/views/example.smarty
+View::forge('example.smarty');
+
+// load a Dwoo template, ATTENTION: this one expects app/views/example.tpl
+View::forge('example.dwoo');
+```
+
+## Installing parsers
+
+Only Markdown is included. While many other drivers are included, their libraries are not and are by default.
+
+Mustache, Twig, MtHaml and Smarty should be installed via Composer. Simply add the libraries to your project's `composer.json` then run `php composer.phar install`:
+
+```json
+{
+    "require": {
+        "mustache/mustache" : "*",
+        "smarty/smarty" : "*",
+        "twig/twig" : "*",
+        "mthaml/mthaml": "*"
+    }
+}
+```
+
+Other libraries are expected in `app/vendor/lib_name` (capitalize lib_name), you'll have to download them yourself. Don't change the casing or anything, keep it as much original as possible within the `vendor/lib_name` dir to keep updating easy (also because some come with their own autoloader).
+
+You can configure them to be loaded from other locations by copying the parser.php config file to your app and editing it.
+
+## Config and runtime config
+
+Currently the drivers still lack a lot of config options they should probably accept. They are currently all configured to work with one instance of their parser library, which is available to config:
+
+```php
+$view = View::forge('example.stags');
+$view->parser()->set_delimiters('{', '}');
+```

+
+PHP Markdown Extra
+==================
+
+Description
+-----------
+
+This is a PHP port of the original Markdown formatter written in Perl 
+by John Gruber. This special "Extra" version of PHP Markdown features 
+further enhancements to the syntax for making additional constructs 
+such as tables and definition list.
+
+Markdown is a text-to-HTML filter; it translates an easy-to-read /
+easy-to-write structured text format into HTML. Markdown's text format
+is mostly similar to that of plain text email, and supports features such
+as headers, *emphasis*, code blocks, blockquotes, and links.
+
+Markdown's syntax is designed not as a generic markup language, but
+specifically to serve as a front-end to (X)HTML. You can use span-level
+HTML tags anywhere in a Markdown document, and you can use block level
+HTML tags (like <div> and <table> as well).
+
+For more information about Markdown's syntax, see:
+
+<http://daringfireball.net/projects/markdown/>
+
+

+expected; (3) the output Markdown actually produced.
