 <h1>Using CodeIgniter Drivers</h1>
 
 
-<p>Drivers are a special type of Library that has a parent class and any number of potential child classes. Child classes have access to the parent class, but not their siblings. Drivers provide an elegant syntax in your <a href="controllers.html">controllers</a> for libraries that benefit from or require being broken down into discrete classes.</p>

 <p>To use a driver you will initialize it within a controller using the following initialization function:</p>
 
 <code>$this->load->driver('<var>class name</var>'); </code>
 
-<p>Where <var>class name</var> is the name of the driver class you want to invoke. For example, to load a driver named "Some Parent" you would do this:</p>
