+How to Add Captcha Widget
+=========================
+
+In order to add the Yii 2 captcha widget you need to: 
+
+- Override the Form class you wish to add the captcha rule to
+- Override the view where the form is rendering 
+- Add captcha action to a controller
+- Configure Module and Application
+
+
+Override the Form 
+-----------------
+
+For the sake of the example, we are going to override the `Da\User\Form\RecoveryForm` class: 
+
+```php 
+namespace app\forms;
+
+class RecoveryForm extends Da\User\Form\RecoveryForm {
+    
+    public $captcha;
+    
+    public function rules() {
+    
+        $rules = parent::rules();
+        
+        $rules[] = ['captcha', 'required'];
+        $rules[] = ['captcha', 'captcha'];
+        
+        return $rules;
+    }
+}
+
+```
+
+Overriding the View
+-------------------
+
+Create a new file and name it `request.php` and add it in `@app/views/user/recovery`. Add the captcha widget to it: 
+
+```php 
+<?php
+
+use yii\helpers\Html;
+use yii\widgets\ActiveForm;
+use yii\captcha\Captcha;
+
+/**
+ * @var yii\web\View $this
+ * @var yii\widgets\ActiveForm $form
+ * @var \Da\User\Form\RecoveryForm $model
+ */
+
+$this->title = Yii::t('usuario', 'Recover your password');
+$this->params['breadcrumbs'][] = $this->title;
+?>
+<div class="row">
+    <div class="col-md-4 col-md-offset-4 col-sm-6 col-sm-offset-3">
+        <div class="panel panel-default">
+            <div class="panel-heading">
+                <h3 class="panel-title"><?= Html::encode($this->title) ?></h3>
+            </div>
+            <div class="panel-body">
+                <?php $form = ActiveForm::begin(
+                    [
+                        'id' => $model->formName(),
+                        'enableAjaxValidation' => true,
+                        'enableClientValidation' => false,
+                    ]
+                ); ?>
+
+                <?= $form->field($model, 'email')->textInput(['autofocus' => true]) ?>
+                
+                <?= $form->field($model, 'captcha')
+                    ->widget(Captcha::className(), ['captchaAction' => ['/site/captcha']]) ?>
+
+                <?= Html::submitButton(Yii::t('usuario', 'Continue'), ['class' => 'btn btn-primary btn-block']) ?><br>
+
+                <?php ActiveForm::end(); ?>
+            </div>
+        </div>
+    </div>
+</div>
+
+```
+
+Add Captcha Action to a Controller
+----------------------------------
+
+```php 
+
+namespace app\controllers;
+
+class RecoveryController extends \yii\web\Controller
+{
+    // ...
+    
+    public function actions()
+    {
+        return [
+            'captcha' => [
+                'class' => 'yii\captcha\CaptchaAction',
+            ],
+        ];
+    }
+    
+    // ...
+}
+
+```
+
+Configure Module and Application
+--------------------------------
+
+Finally, we have to configure the module and the application to ensure is using our form and our view: 
+
+```php
+
+// ... 
+
+'modules' => [
+    'user' => [
+        'class' => Da\User\Module::class,
+        'classMap' => [
+            'RecoveryForm' => 'app\forms\RecoveryForm'
+        ]
+    ]
+], 
+
+// ...
+
+'components' => [
+    'view' => [
+        'theme' => [
+            'pathMap' => [
+                '@Da/User/resources/views' => '@app/views/user'
+            ]
+        ]
+    ]
+]
+
+```
