Woocommerce – How to add short description under product titel in shop page

Hi

I am using the woocommerce plugin and I want to Show the short product description under the product title on the page where all products are listed.

I tried some codes I’ve found on the web but nothing worked so far.
(for example this one: https://support.truethemes.net/?knowledgebase=add-short-descripton-to-products-in-shop-page)
Can anybody help?

Please be beginner-friendly in your Response ??

Thanks in advance!
