Woocommerce Customize shop page

Hi all, i have been working on my site now and step by step learning how this all works. For now i am working on my Shop page and i want to make some changes. (https://imgur.com/a/9fC5x)

I’d like the items to have some information put either under or besides it so i gues then it should be best to have maybe 2 or max 3 products per row.

More important i think is to change the page in the right place. I have a child theme but if i look on the internet the child themes have maps like woocommerce in them. My child theme only has a style.css file is it. What else should i have in this CT map.

Thanks for your time and almost happy weekend,

Sjoerd
