Krak Validation
===============

[](#krak-validation)

The Krak Validation library is a functional and simple approach and interface to validation. It was made out of the need a validation library with a simple interface and configuration. Other leading validators like Respect, Zend, or Symfony have a lot of complexity in their API and adding an actual validator will require adding several classes in some instances.

Krak Validation changes all of this by taking a functional approach to validation where every validator is just a function or instance of `Krak\Validation\Validator`. This design lends itself easily for extending, custom validators, and decorators. It comes bundled with a `Krak\Validation\Kernel` which manages validators to provide a simple, fluent, and customizable interface for utilizing validators.
