Child Theme – Slider gallery help

Hello,

I’m fairly new to word press and hoping to get some help here.

I just created a child theme off the Responsive theme. I’m trying to understand how to use a image slider plug such as the FlexSlider for the theme. Do I create a new folder in the child theme or directly in the Parent theme? I tried googling it online but couldn’t find a solution.

If anyone can please help or direct me to links, it be awesome.

Thanks.
