slider for home page of edu blog

I was speaking to sarah in chat, i want add a slider and have downloaded a plugin on to my dashboard, it is asking me to post he following code,, were do i put it so that the slider appears at the top of my home page.

I have tried index-home.php but all that happens is the code appears on my website.

My website is using the edublog theme.

if ( function_exists( 'get_wp_parallax_content_slider' ) ) { get_wp_parallax_content_slider(); }

Thanks for you support
