Xenforo | RSS Xenforo: How to make it look like this?

I'm new to xenforo, so please anyone tell me how can I make the forum look like this:

https:// www. avsforum . com/
or
https:// www. dealsforum. com/

they have recommended and stick topic on the homepage instead of the deafault new post~~~
do they use some kind of template or what ?
