+# Database proxy
+
+Ok, so you want to proxy the database.
+
+Install this module, and decorate the factory with code you want to extend
+
+```
+---
+Name: myproxydb
+After: '#proxydb'
+---
+TractorCow\SilverStripeProxyDB\ProxyDBFactory:
+  extensions:
+    - ProxyDBExtension
+```
+
+Then in your code you can do this
+
+```
+<?php
+
+use SilverStripe\Core\Extension;
+use TractorCow\ClassProxy\Generators\ProxyGenerator;
+
+class ProxyDBExtension extends Extension
+{
+    public function updateProxy(ProxyGenerator &$proxy)
+    {
+        $proxy = $proxy->addMethod('manipulate', function ($args, $next) {
+            SearchManipulator::manipulate($args[0]);
+            return $next(...$args);
+        });
+    }
+}
+```
+
+You can chain methods; All addMethod() calls on the same method name will 
+form a set of middleware. First methods registered are executed first.
