 How to Use the submit() Function to Handle Form Submissions
 ===========================================================
 
-Handle the form submission with the ``handleRequest()`` method::
+The recommended way of :ref:`processing Symfony forms <processing-forms>` is to
+use the :method:`Symfony\\Component\\Form\\FormInterface::handleRequest` method
+to detect when the form has been submitted. However, you can also use the
+:method:`Symfony\\Component\\Form\\FormInterface::submit` method to have better
+control over when exactly your form is submitted and what data is passed to it::
 
     use Symfony\Component\HttpFoundation\Request;
     // ...
 
     public function new(Request $request)
     {
-        $form = $this->createFormBuilder()
-            // ...
-            ->getForm();
-
-        $form->handleRequest($request);
-
-        if ($form->isSubmitted() && $form->isValid()) {
-            // perform some action...
