Removing 'Kriesi' backlink in footer.

Hi, I have finally got onto ENfold, am very excited!

I saw from other posts to add this in functions.php

but because I don;t know how to code I don;t know where to put this:

add_filter(“kriesi_backlink”,”new_link”);
function new_link(){
$kriesi_at_backlink = “”;
return $kriesi_at_backlink;
}

I understand I can use [no backlink] in the footer copyright options but I wanted to put other info there too.

What’s the best way to do this?
