# Why

The purpose of this library is to provide an access to the CodeIgniter's instance that is based on this [link](codeinphp.github.io/post/codeigniter-tip-accessing-codeigniter-instance-outside/). I just package this via [Composer](https://getcomposer.org/) for easy access. This may help you in developing libraries for CodeIgniter that does not go through ```index.php```, giving you more flexibility to your application.

I used this package as a dependency for [Combustor](https://github.com/rougin/combustor) and [Refinery](https://github.com/rougin/refinery).
