+Using Personal translations with Symfony2 forms
+==============================================
+
+Example code to transform a Symfony2 form into an i18n Forms using Personal Translations
+
+For example we have an Entity Product and its counterpart for Personal Translations
+
+Product Entity
+-------------
+
+::
+
+    namespace ExampleBundle\Entity
+    
+    use Doctrine\ORM\Mapping as ORM;
+    use Doctrine\Common\Collections\ArrayCollection;
+    use Gedmo\Mapping\Annotation as Gedmo;
+    use Symfony\Component\Validator\Constraints as Assert;
+    
+     /**
+     * @ORM\Entity
+     */
+    class Product
+    {
+        /**
+         * @var string $title
+         *
+         * @ORM\Column(name="title", type="string", length=255)
+         */
+        protected $title;
+    
+        /**
+         * @var string $description
+         *
+         * @ORM\Column(name="description", type="text")
+         */
+        protected $description;
+
+        /**
+         * @var $translations
+         *
+         * @ORM\OneToMany(targetEntity="ExampleBundle\Entity\Translation\ProductTranslation", mappedBy="object", cascade={"persist", "remove"})
+         */
+        protected $translations;
+    
+        /**
+         * Constructor is needed for providing an usable translations variable
+         */
+        public function __construct()
+        {
+            $this->translations = new ArrayCollection();
+        }
+    
+        /**
+         * Adds a Translation to Product
+         *
+         * @param ExampleBundle\Entity\Translation\ProductTranslation
+         */
+        public function addTranslation(Translation\ProductTranslation $t)
+        {
+            if (! $this->translations->contains($t)) {
+                $this->translations[] = $t;
+                $t->setObject($this);
+            }
+        }
+    }
+    
+Product Translation
+-------------------
+
+::
+
+    namespace ExampleBundle\Entity\Translation;
+
+    use Doctrine\ORM\Mapping as ORM;
+    use Gedmo\Translatable\Entity\MappedSuperclass\AbstractPersonalTranslation;
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    /**
+     * @ORM\Entity
+     * @ORM\Table(name="product_translations",
+     *     uniqueConstraints={@ORM\UniqueConstraint(name="lookup_unique_idx", columns={
+     *         "locale", "object_id", "field"
+     *     })}
+     * )
+     */
+    class ProductTranslation extends AbstractPersonalTranslation
+    {
+        /**
+         * @ORM\ManyToOne(targetEntity="ExampleBundle\Entity\Product" inversedBy="translations")
+         */
+        protected $object;
+    
+        /**
+         * @ORM\Column(name="content", type="text", length=255)
+         */
+        protected $content;
+    }
+
+Simple (Sonata) Form
+--------------------
+
+::
+
+    protected function configureFormFields(FormMapper $formMapper)    {
+        $formMapper
+            ->with('General')
+            ->add('title', 'text')
+            ->add('description', 'textarea')
+            ->end()
+    }
+
+To simple transform it into an i18n form use the follow files from https://gist.github.com/2437078 and
+integrate it into your bundle
+
+::
+
+    https://gist.github.com/2437078
+
+    <Bundle>/Form/TranslatedFieldType.php
+    <Bundle>/Form/EventListener/addTranslatedFieldSubscriber.php
+    <Bundle>/Resources/services.yml
+
+Then after changing your form definition to:
+
+::
+
+    protected function configureFormFields(FormMapper $formMapper)
+    {
+        $formMapper
+            ->with('General')
+                ->add('title', 'translatable_field', array(
+                     'field'                => 'title',
+                     'personal_translation' => 'ExampleBundle\Entity\Translation\ProductTranslation',
+                     'property_path'        => 'translations',
+                ))
+                ->add('description', 'translatable_field', array(
+                     'field'                => 'description',
+                     'personal_translation' => 'ExampleBundle\Entity\Translation\ProductTranslation',
+                     'property_path'        => 'translations',
+                     'widget'               => 'textarea',
+                ))
+            ->end()
+        ;
+    }
+
+you have a simple i18n form.
+
+
+Validation
+==========
+
+Every field can have its own Validation, but it needs to be provided on the Personal Translation entity,
+in the example you can provide a Validation with annotation like:
+
+::
+
+    class ProductTranslation extends AbstractPersonalTranslation
+    {
+        /**
+         * @Assert\MinLength(limit=3, groups={"title:en", "title:nl"})
+         * @Assert\MaxLength(limit=2048, groups={"description:nl"})
+         * @Assert\MaxLength(limit=1024, groups={"description:en"})
+         *
+         * @ORM\Column(name="content", type="text", length=255)
+         */
+        protected $content;
+    }
+
+Adding or Changing a Language
+=============================
+In the file
+::
+
+    <Bundle>/Form/TranslatedFieldType.php
+
+To change all the languages application-wide you can adjust
+the variable "locales" to you needs
