## Get Started

### Downloading the prebuilt files

 2. [Setup the build](CONTRIBUTING.md#build-setup)
 3. Run `grunt` to create the built files in the "dist" directory

### Including it on your page

Include jQuery and the plugin on a page. Then select a form to validate and call the `validate` method.

```html

<script src="jquery.js"></script>
<script src="jquery.validate.js"></script>
<script>
$("form").validate();

```js
define(["jquery", "jquery.validate"], function( $ ) {
	$("form").validate();
});
```

## Reporting issues and contributing code

See the [Contributing Guidelines](CONTRIBUTING.md) for details.

**IMPORTANT NOTE ABOUT EMAIL VALIDATION**. As of version 1.12.0 this plugin is using the same regular expression that the [HTML5 specification suggests for browsers to use](https://html.spec.whatwg.org/multipage/forms.html#valid-e-mail-address). We will follow their lead and use the same check. If you think the specification is wrong, please report the issue to them. If you have different requirements, consider [using a custom method](http://jqueryvalidation.org/jQuery.validator.addMethod/).
