Homepage Settings problem

Hi..

I have the image slider (revolution slider) and I want to put it on my home page.

In the folder of Rev. Slider is said how to do that, but I need some technical help.

For show only on homepage use: <?php putRevSlider(“SonoSlider”,”homepage”) ?>

This is written and I don´t know how to use that code and where I need to paste it that my slider will be visible and active on my homepage.

Need help,
Thanks!
