+# Origami Catpcha - Laravel Google ReCaptcha Integration
+
+This package adds a validation rule and controller trait for easier integration with Google Recaptcha
+
+## Installation
+
+Install this package through Composer.
+
+```
+composer require origami/captcha
+```
+
+### Requirements
+
+This package is designed to work with Laravel >= 5.4 currently.
+
+### Service Provider
+
+If you do not have package auto discovery, there is a Laravel 5 is a service provider you can make use of to automatically prepare the bindings.
+
+```php
+
+// app/config/app.php
+
+‘providers’ => [
+    ...
+    Origami\Consent\ConsentServiceProvider::class
+];
+```
+
+### Setup
+
+1. Signup for a Google Recaptcha account at https://www.google.com/recaptcha/admin
+
+2. You should add a recatpcha section to your `config/services.php` file:
+
+```php
+
+    'recaptcha' => [
+        'key' => env('RECAPTCHA_KEY'),
+        'secret' => env('RECAPTCHA_SECRET'),
+    ],
+
+```
+
+3. Update your `.env` file with the key and secret:
+
+```
+RECAPTCHA_KEY=
+RECAPTCHA_SECRET=
+```
+
+4. Add a language line to your validation file(s), e.g. `resources/lang/en/validation.php`
+
+```
+
+    'recaptcha' => 'The reCAPTCHA check was invalid',
+
+```
+
+## Usage
+
+### Validator
+
+```php
+$validator = Validator::make($request->all(), [
+    'recaptcha' => 'recaptcha',
+]);
+```
+
+### Controller Validation
+
+(Assuming your Controller has the `ValidatesRequests` trait)
+
+```php
+class Contact extends Controller
+{
+    public function store(Request $request)
+    {
+        $this->validate($request, [
+            'recatpcha' => 'recaptcha'
+        ]);
+    }
+}
+```
+
+### Controller with ValidatesCaptcha Trait
+
+```php
+
+use Origami\Captcha\ValidatesCaptcha;
+
+class Contact extends Controller
+{
+    use ValidatesCaptcha;
+
+    public function store(Request $request)
+    {
+        $this->validateCatpcha($request);
+
+        // The above will throw a ValidationException when the recaptcha fails.
+    }
+
+}
+```
+
+## Blade Helpers
+
+This packages registers two Blade helpers:
+
+`@recaptchaField` is the equivalent of:
+
+```
+<div class="g-recaptcha" data-sitekey="{{ config('services.recaptcha.key') }}"></div>
+```
+
+`@recaptchaScript` is the equivalent of:
+
+```
+<script src="https://www.google.com/recaptcha/api.js"></script>
+```
