+# Overview
+
+For helpful resources on overriding Magento controllers, blocks, models, helpers, etc. see Josh Pratt's post on [Magento: Overriding Core Files (Blocks, Models, Resources, Controllers)](http://prattski.com/2010/06/24/magento-overriding-core-files-blocks-models-resources-controllers/)
+
+Here's a [list of search results](http://bit.ly/1pMvExF) that I've found most helpful; otherwise good luck with the Googling! 
+
+## Overriding Controllers
+
+### Overriding Magento Core Admin controllers
+
+```xml
+<!-- in your app/code/local/etc/config.xml file -->
+<config>
+    <admin>
+        <routers>
+            <adminhtml>
+                <args>
+                    <modules>
+                        <My_Module before="Mage_Adminhtml">My_Module</My_Module>
+                    </modules>
+                </args>
+            </adminhtml>
+        </routers>
+    </admin>
+</config>
+```
+
+**And don't forget to `include_once` or `require_once` the parent controller!**
+
+```php
+<?php
+
+// explicitly require parent controller b/c controllers are not autoloaded
+require_once(Mage::getModuleDir('controllers','Mage_Adminhtml') .DS. 'Catalot' .DS. 'Product' .DS. 'AttributeController.php');
+
+class My_Module_Adminhtml_Catalog_Product_AttributeController extends Mage_Adminhtml_Catalog_Product_AttributeController
+{
+...
+}
+```
+
+### Overriding Community module's Admin controllers 
+
+In this example, the community module will be the `Xtento_GridActions` module and specifically the `Xtento_GridActions_Adminhtml` controllers.
+
+```xml
+<!-- in your app/code/local/etc/config.xml file -->
+<config>
+    <admin>
+        <routers>
+            <adminhtml>
+                <args>
+                    <modules>
+                        <My_Module before="Xtento_GridActions_Adminhtml">My_Module_Adminhtml</My_Module>
+                    </modules>
+                </args>
+            </adminhtml>
+        </routers>
+    </admin>
+</config>
+```
+
+**And don't forget to `include_once` or `require_once` the parent controller!**
+
+```php
+<?php
+
+// explicitly require parent controller b/c controllers are not autoloaded
+require_once(Mage::getModuleDir('controllers','Xtento_GridActions') .DS. 'Adminhtml' .DS. 'Gridactions' .DS. 'PrintController.php');
+class MY_MODULE_Adminhtml_Gridactions_PrintController extends Xtento_GridActions_Adminhtml_GridActions_PrintController
+{
+...
+}
+```
