woocommerce product attributes

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?

A look at the documentation or the source is always helpful. I guess, the correct file to refer to would have been product-attributes.php. For getting the product attributes this is available: get_attribute() ; to list them list_attributes() can be used, which makes use of the product-attributes.php template. You can use those and then hook into the fitting one to display the attributes. To learn more about hooks give the Plugin API a good thorough read.
