archive-template.php

// for practical purposes I have called this template archive-template
but if your custom post type category is moves you would call this archive-movies.php.

I have set the posts to 9, but you can set it to however many you want. 

 $paged = ( get_query_var('paged')) ? get_query_var('paged') : 1;
					             $args = array(
					                'post_type' => 'insight',
					                'post_status' => 'publish',
					                'posts_per_page' => 9,
					                'paged' => $paged,
                          'order' => 'DESC',
					            );


// after your loop/endif statement, call in the pagination function using a div class of pagination

<div class="pagination"><?php pagination('»', '«'); ?></div>
