Forgive me if someone has asked this before, but i am trying to get some attributes displayed next to displayed content of product. I see the hook woocommerce_before_single_product_summary that displayed few attributes but not all. The woocommerce_before_single_product_summary let me back to directory structure in woo/templates/single-products/filename which is just

  if ( ! defined( \'ABSPATH\' ) ) exit; // Exit if accessed directly

global $post, $product;
if ($product->is_on_sale()) :

apply_filters(\'woocommerce_sale_flash\', \'<span class="onsale">\'.__( \'Sale!\', \'woocommerce\' ).\'</span>\', $post, $product); ?>
endif;

Now i am lost, where do i go from here? How do i add my attributes to my product-catalog and single product page? Where do i go from the apply_filters? How do i find the generated html for the attributes?
