+### Usage
+
+#### Request Validation
+
+The `RequestValidation` middleware will validate or invalidate incoming requests and let you decide how to react.
+You can precede it with your own custom middleware or precede it with one of the following built-in options:
+
+#### Nested Json Response
+
+The `ResponseJsonNested` MUST precede the `RequestValidation` middleware
+as it relies on the container containing the result.
+It will check whether the request has passed or failed validation.
+Invalid requests will return a response detailing the reasons the request was invalid.
 
-To validate requests for all your routes, add the `RequestValidation` middleware to `$middleware` property
-of  `app/Http/Kernel.php` class:
+#### Flat Json Response
+
+The `ResponseJsonFlat` MUST precede the `RequestValidation` middleware 
+as it relies on the container containing the result.
+It will check whether the request has passed or failed validation.
+Invalid requests will return a response detailing the reasons the request was invalid.
+
+### Global Usage
 
 ```php
 protected $middleware = [
   \Membrane\Laravel\RequestValidation::class,
     // ...
 ];
 ```
