+You have to pass the `validator` prop which is your form object's Vuelidate validation. 
+Its a good practice to wrap your forms in an object like so:
+
+```js
+export default {
+  data() {
+    return {
+      form: {
+        name: '',
+        email: ''
+      }
+    }
+  },
+  validations: {
+    form: {
+      name: { required },
+      email: { required, email }
+    }
+  }
+}
+```
+By adding a `messages` prop, you can override the globally defined messages.

 ### Single Error Extractor
 When using with the `SingleErrorExtractor` component, its required to pass а **name** prop to each error extractor. That is a string representing the field's key in the form.
 
 That way the `singleErrorExtractor` can look into the `formWrapper` validator and get the proper validations.
  
-Using the name prop, the error message `attribute` is guessed from the global `$vuelidateErrorExtractor.attributes` object. 
+Using the `name` prop, the error message `attribute` is guessed from the global `$vuelidateErrorExtractor.attributes` object.
