 ### Setup
 
-Add ServiceProvider to the providers array in `app/config/app.php`.
+**_NOTE_** This package supports the auto-discovery feature of Laravel 5.5, So skip these `Setup` instructions if you're using Laravel 5.5.
 
-```
+In `app/config/app.php` add the following :
+
+1- The ServiceProvider to the providers array :
+
+```php
 Anhskohbo\NoCaptcha\NoCaptchaServiceProvider::class,
 ```
 
+2- The class alias to the aliases array :
+
+```php
+'NoCaptcha' => Anhskohbo\NoCaptcha\Facades\NoCaptcha::class,
+```
+
 ### Configuration
 
-Add `NOCAPTCHA_SECRET` and `NOCAPTCHA_SITEKEY` in **.env** file (without brackets):
+Add `NOCAPTCHA_SECRET` and `NOCAPTCHA_SITEKEY` in **.env** file :
 
 ```
 NOCAPTCHA_SECRET=secret-key
 NOCAPTCHA_SITEKEY=site-key
 ```
 
+(You can obtain them from [here](https://www.google.com/recaptcha/admin))
+
 ### Usage
 
-##### Init js source
+#### Init js source
 
-```
- {!! app('captcha')->renderJs($lang = 'en', $callback = false, $onLoadClass = 'recaptchaCallback') !!}
+With default options :
+
+```php
+ {!! NoCaptcha::renderJs() !!}
 ```
 
-##### Display reCAPTCHA
+With [language support](https://developers.google.com/recaptcha/docs/language) or [onloadCallback](https://developers.google.com/recaptcha/docs/display#explicit_render) option :
 
 ```php
-{!! app('captcha')->display(); !!}
+ {!! NoCaptcha::renderJs('fr', true, 'recaptchaCallback') !!}
 ```
 
-With custom attributes and language support:
+#### Display reCAPTCHA
+
+Default widget :
 
+```php
+{!! NoCaptcha::display() !!}
 ```
-{!! app('captcha')->display($attributes = []); !!}
+
+With [custom attributes](https://developers.google.com/recaptcha/docs/display#render_param) (theme, size, callback ...) :
+
+```php
+{!! NoCaptcha::display(['data-theme' => 'dark']) !!}
 ```
 
-##### Validation
+#### Validation
 
-Add `'g-recaptcha-response' => 'required|captcha'` to rules array.
+Add `'g-recaptcha-response' => 'required|captcha'` to rules array :
 
 ```php
-
 $validate = Validator::make(Input::all(), [
 	'g-recaptcha-response' => 'required|captcha'
 ]);
 
 ```
 
-### Testing
+##### Custom Validation Message
 
-When using the [Laravel Testing functionality](http://laravel.com/docs/5.1/testing), you will need to mock out the response for the captcha form element. To do this:
+Add the following values to the `custom` array in the `validation` language file :
 
-1) Setup NoCaptcha facade in config/app.conf
+```php
+'custom' => [
+    'g-recaptcha-response' => [
+        'required' => 'Please verify that you are not a robot.',
+        'captcha' => 'Captcha error! try again later or contact site admin.',
+    ],
+],
+```
+
+Then check for captcha errors in the `Form` :
 
 ```php
-'NoCaptcha' => 'Anhskohbo\NoCaptcha\Facades\NoCaptcha'
+@if ($errors->has('g-recaptcha-response'))
+    <span class="help-block">
+        <strong>{{ $errors->first('g-recaptcha-response') }}</strong>
+    </span>
+@endif
 ```
 
-2) For any form tests involving the captcha, you can then mock the facade behaviour:

+
+When using the [Laravel Testing functionality](http://laravel.com/docs/5.5/testing), you will need to mock out the response for the captcha form element.
+
+So for any form tests involving the captcha, you can do this by mocking the facade behavior:
 
 ```php
 // prevent validation error on captcha
 NoCaptcha::shouldReceive('verifyResponse')
     ->once()
     ->andReturn(true);
+
 // provide hidden input for your 'required' validation
 NoCaptcha::shouldReceive('display')
