## Getting Started

### Downloading the latest changes
|
|
|

The unreleased development files can be obtained by:

### 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
|
|
<form>
|
|
<input required>
|
|
</form>
|
|
<script src="jquery.js"></script>
|
|
<script src="jquery.validate.js"></script>
|
|
<script>
|
|
$("form").validate();
|
|
</script>
|
|
```
|
|
|
|
Alternatively include jQuery and the plugin via requirejs in your module.
|
|
|
|
```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/).
|
|
In case you need to adjust the built-in validation regular expression patterns, please [follow the documentation](http://jqueryvalidation.org/jQuery.validator.methods/).
