 This behavior can be easily disabled by setting `SimpleRouter::enableMultiRouteRendering(false)` in your `routes.php` file. This is the same behavior as version 3 and below.
 
+## Restrict access to IP
+
+You can white- and blacklist access to IP's using the build in `IpBlockAccess` middleware.
+
+Create your own Middleware and extend the `IpBlockAccess` class.
+
+You can use `*` to restrict access to a range of ips.
+
+```php
+use \Pecee\Http\Middleware\IpBlockAccess;
+
+class IpBlockMiddleware extends IpBlockAccess {
+
+    protected $ipBlacklist = [
+        '5.5.5.5',
+        '8.8.*',
+    ];
+
+    protected $ipWhitelist = [
+        '8.8.2.2',
+    ];
+
+}
+```
