 To achieve this, it is important that the plugin is actually deployed on websites around the world, so a lot of focus is spent on making it easy for developers - that's you - to use the plugin.

 # Markup recommendations
 Mandated: A 'name' attribute is required for all input elements needing validation, and the plugin will not work without this. A 'name' attribute must also be unique to the form, as this is how the plugin keeps track of all input elements. However, each group of radio or checkbox elements will share the same 'name' since the value of this grouping represents a single piece of the form data.

 # Methods
-A validation method implements the logic to validate any element. Provided are a set of default validation methods, such as required. Apart from required itself and equalTo, all validation methods declare an element valid when it has no value at all. That way an email field is optional unless required is specified. You can specify an element input to contain a valid email address, or nothing at all. Use <a href="/jQuery.validator.addMethod/">jQuery.validator.addMethod</a> to implement custom methods.

 # Rules
 A validation rule applies one or more validation methods to an input element. You can specify validation rules via metadata or via plugin settings (option `rules`). The decision is often influenced by serverside infrastructure. If a web framework is used, it is often easier to use metadata, which is also good for fast prototyping. Plugin settings produce cleaner markup, though valid markup results from both.

 ## Refactoring rules

 Let's consider an example where you have ten customer fields, each required and with a minlength of 2. You need custom messages for both rules. To avoid having to specify those rules and messages again and again, we can alias existing methods with different messages and group them into a single class:
