Texts in Categories

Dear all,

I have installed the Affipress Theme, a shop-a-like theme. On the starting page it is possible to add some additional text below the products by feeding the index.php file. Please have a look at the starting-page: mein-bollerwagen.com. I’d like to do the same on the category page (e.g. mein-bollerwagen.com/category/faltbare-bollerwagen) but I don’t know how. I can just add some text above the products. Is it possible to do it from anywhere in the backend? Or do I have to check the FTP files? Sorry but I’m not very good in programming;-) Greetings from Germany!

Thanks a lot in advance!
