Pagination Plugin

Is it possible to use this plugin (link below) with the BlogsTrend theme?

http://wordpress.org/extend/plugins/wp-paginate/

If so, where would I do the editing they specify (link below). It doesn't appear to be in any of the files they list:

http://wordpress.org/extend/plugins/wp-paginate/installation/

 

After activating plugin
Open index.php file and add

Code:

<?php if(function_exists('wp_paginate')) {
    wp_paginate();
} ?>

In place of

Code:

 <?php inkthemes_pagination(); ?>

As shown in image.


Thanks.
