Hi,
You will have to adjust the loop that the code generates for the homepage, you can use something like this in the template file
<ul class="products">
<?php
global $paged;
$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;
$args = array(
'post_type' => 'product',
'posts_per_page' => 4,
'paged' => $paged
);
$loop = new WP_Query( $args );
if ( $loop->have_posts() ) {
while ( $loop->have_posts() ) : $loop->the_post();
woocommerce_get_template_part( 'content', 'product' );
endwhile;
} else {
echo __( 'No products found' );
}
?>
<nav>
<ul>
<li><?php previous_posts_link( '« PREV', $loop->max_num_pages) ?></li>
<li><?php next_posts_link( 'NEXT »', $loop->max_num_pages) ?></li>
</ul>
</nav>
<?php wp_reset_postdata(); ?>
</ul><!--/.products-->
