+This bundle provide the following custom form types:
+
+## SwitchType
+
+The `SwitchType` type has the same behavior as the `CheckboxType` type and allows to display a checkbox as a [toggle switch](https://flowbite.com/docs/components/forms/#toggle-switch):
+
+```php
+namespace App\Form;
+
+use TalesFromADev\FlowbiteBundle\Form\Type\SwitchType
+
+class TemplateType extends AbstractType
+{
+    public function buildForm(FormBuilderInterface $builder, array $options): void
+    {
+        $builder
+            ->add('switch', SwitchType::class)
+        ;
+    }

+# Theme customization
+
+## Overriding CSS classes
+
+All used CSS classes are contained in [Twig blocks](https://github.com/talesfromadev/flowbite-bundle/blob/main/templates/form/default.twig#L244) 
+which allows to customize the theme very easily.
+
+Create a new theme in your `templates` directory and make it use the bundle `default` theme: 
+
+```php
+# templates/form/layout.html.twig
+
+{% use '@Flowbite/form/default.html.twig' %}
+```
+
+Now, just override the desire block with any Tailwind CSS class you want:
+
+```php
+# templates/form/layout.html.twig
+
+{% use '@Flowbite/form/default.html.twig' %}
+
+{% block class_submit -%}
+    # use any Tailwind CSS class you want ...
+{%- endblock class_submit %}
+```
+

+
+* Label
+  * class_label
+  * class_input_radio_label
