+# Configuration
+
+**Important:** Before you start declaring a configuration you should [lookup how HTML Purifier can be configured](http://htmlpurifier.org/docs).
+
+In `config/bootstrap.php` you can either set the purifier config as an array or pass a native config object.
+
+The array style would look like this:
+
+```php
+// Don't forget to add the `use` statement
+use Burzum\HtmlPurifier\Lib\Purifier;
+
+Purifier::config('ConfigName', array(
+        'HTML.AllowedElements' => 'a, em, blockquote, p, strong, pre, code, span,ul,ol,li,img',
+        'HTML.AllowedAttributes' => 'a.href, a.title, img.src, img.alt'
+    )
+);
+```
+
+The plugin will construct a HTML Purifier config from that and instantiate the purifier.
+
+A pure HTML Purifier config might look like this one:
+
+```php
+$config = HTMLPurifier_Config::createDefault();
+$config->set('HTML.AllowedElements', 'a, em, blockquote, p, strong, pre, code, span,ul,ol,li,img');
+$config->set('HTML.AllowedAttributes', 'a.href, a.title, img.src, img.alt');
+$config->set('HTML.AllowedAttributes', "*.style");
+$config->set('CSS.AllowedProperties', 'text-decoration');
+$config->set('HTML.TidyLevel', 'heavy');
+$config->set('HTML.Doctype', 'XHTML 1.0 Transitional');
+```
+
+Simply assign it to a config:
+
+```php
+Purifier::config('ConfigName', $config);
+```
+
+Now that you have a configured instance of HTML Purifier ready you can use it directly and get you an instance of the purifier
+
+```php
+Purifier::config('ConfigName');
+```
+
+or clean some dirty HTML directly by calling
+
+```php
+Purifier::clean($markup, 'ConfigName');
+```
+
+## Caching ###
+
+It is recommended to change the path of the purifier libs cache to your `tmp` folder. For example:
+
+```php
+Purifier::config('ConfigName', array(
+        'Cache.SerializerPath' => ROOT . DS . 'tmp' . DS . 'purifier',
+    )
+);
+```
+
+See this page as well http://htmlpurifier.org/live/configdoc/plain.html#Cache.

+# If you use APC ...

+...and get this error message
+
+	Fatal error: Cannot override final method HTMLPurifier_VarParser::parse()
+
+you can fix this by adding
+
+```php
+Configure::write('HtmlPurifier.standalone', true);
+```
+
+to your bootstrap.php *before* you load this plugin.
+
+This line will use a compacted one file version of Html Purifier. This is an official and know issue and workaround, see http://htmlpurifier.org/phorum/read.php?3,4099,6680.
