+Constraints in Form Classes
+---------------------------
 
-When creating your own form classes, you may want to add constraint directly in the formBuilder.
-This is done by simply adding them as a parameter in your field options::
+Constraints can be defined while building the form via the ``constraints`` option
+of the form fields::
 
     public function buildForm(FormBuilderInterface $builder, array $options)
     {
         $builder
-            ->add('myField', TextType::class, ['required' => true, 'constraints' => [new Length(['min' => 3])]])
+            ->add('myField', TextType::class, array(
+                'required' => true,
+                'constraints' => array(new Length(array('min' => 3)))
+            ))
     }
 
-Please note the *constraints* keyword will only be available if you have
-added the *ValidatorExtention* to the formBuilder::
+The ``constraints`` option is only available when adding the ValidatorExtention
+to the formBuilder::
 
-    Forms::createFormFactoryBuilder()->addExtension(new ValidatorExtension(Validation::createValidator()))->getFormFactory();
+    Forms::createFormFactoryBuilder()
+        ->addExtension(new ValidatorExtension(Validation::createValidator()))
+        ->getFormFactory()
