+By default, form controls are resetted after `submit` event.
+
+It's possible to deactivate this funcionality by setting `resetAfterSubmit` to `false` on the `Form Options`.
+
+You can find and example [here](https://vue-dynamic-forms-demos.alvarosaburido.dev/reset-after-submit).
+
+```typescript
+export default {
+  data() {
+    return {
+      form: {
+        id: 'my-awesome-form',
+        fields: {
+          name: TextField({
+            label: 'Name',
+          }),
+          email: EmailField({
+            label: 'Email',
+          }),
+        },
+      },
+      options: {
+        resetAfterSubmit: false,
+      },
+    }
+  },
+}
+```
+
+# Manual Reset
+
+It's possible to reset the form controls and validation manually by accesing the `form` reference and calling the methods directly.
+
+```html
+<DynamicForm ref="formRef" :form="form" />
+```
+
+You can see the example [here](https://vue-dynamic-forms-demos.alvarosaburido.dev/reset-form).
+
+## Options API
+
+You can access the dom element ref above by using template refs `this.$ref`
+
+```typescript
+
+methods: {
+    resetForm() {
+        this.$refs.formRef.resetForm
+    }
+}
+
+```
+
+## Composition API
+
+You can access the dom element ref above by using template refs `const formRef = ref(null)`.
+
+::: warning
+Remember to add the ref to the return statement on the `setup` function so it's available on the template.
+:::
+
+```typescript
+
+setup() {
+    const formRef = ref(null);
+
+    function resetForm() {
+      formRef.value.resetForm()
+    }
+
+    return {
+        formRef
+    }
+}
+
+```
