+# Spark Plug
+
+Another way to access CodeIgniter's instance
+
+# Installation
+
+Install ```Spark Plug``` via [Composer](https://getcomposer.org):
+
+```$ composer require rougin/spark-plug```
+
+# 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 created a [Composer](https://getcomposer.org/) package for easy access. This may help you in developing libraries for CodeIgniter that does not go through ```index.php```.
+
+I used this package as a dependency for [Combustor](https://github.com/rougin/combustor) and [Refinery](https://github.com/rougin/refinery).
+
+# Getting Started
+
+```php
+require 'vendor/autoload.php';
+
+use Rougin\SparkPlug\Instance;
+
+$instance = new Instance();
+$codeigniter = $instance->get();
+```
