Adding pagination to custom post query

Hello,

I have a page that displays posts from a specified category.

I have 10 posts showing but I would like there to be pagination for the option to view previous posts.

The code I am using to generate the posts is:

<section class="front-page archives clear">
   <section class="archive">

<?php $query = new WP_Query( array(
			'post_type' => 'post',
			'category_name' => 'press',
			'posts_per_page' => 8,
			'order' => desc
			) ); ?>

<?php while ($query->have_posts()) : $query->the_post(); ?>
  <?php if (empty($post->post_excerpt))
    { ?>
       <div class="news">
	<div class="newsImgPage">
         <?php the_post_thumbnail();?>
        </div>
	<div class="newsTextPage">
	  <h2><?php the_title(); ?></h2>
	  <span class="nDate"><?php the_date( 'F j Y' ); ?></span>
	  <p><?php the_content(); ?></p>
	</div>
       </div>
  <?php }
	else
	{ ?>
	 <div class="news">
	  <div class="newsImgPage">
            <?php the_post_thumbnail();?>
          </div>
	  <div class="newsTextPage">
	   <h2>
            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
           </h2>
	   <span class="nDate"><?php the_date( 'F j Y' ); ?></span>
	   <p><?php the_excerpt(); ?></p>
	  </div>
	 </div>
	<?php
	}
         endwhile; ?>
</section>
</section>

Any help much appreciated

Thanks
