Where do I find the "category class" ?

[Hetko]

Hello,

 

I'm using this tutorial from NemoPS to let my products sort by best sales. 

 

It says you should create a "category.php" file in override/classes put some code in it and then:

 

" (...) Then, to save us some trouble, we will copy the original getProducts() method of the Category class.

It looks like the following, but be sure you copy your own."

 

Where do I find this "Category class" with the "getProducts ()" in it?

 

I'm new to this I hope someone can help.

 

 

Thanks and best regards!
