Newbie question about editing php in WordPress theme

[mcafiero]

Hi, this is my first post here and I'm also new to php, as you are about to see.  

 

I have a WordPress Themed web site: www.markcafiero.com

I don't like the slider on the home page so I installed a new slider plugin which gives me the following instructions: 

How To Use:

* From the theme html use: <?php putRevSlider( "alias" ) ?> example: <?php putRevSlider("TestSlider") ?> 
For show only on homepage use: <?php putRevSlider("TestSlider","homepage") ?> 
For show on certain pages use: <?php putRevSlider("TestSlider","2,10") ?>
* From the widgets panel drag the "Revolution Slider" widget to the desired sidebar
* From the post editor insert the shortcode from the sliders table

So yes, I want to install on my home page, replacing the other.

I found index.php I assume that's the home page. The following is the index.php code. If you can tell me what to replace with the above php code, I'll award you the job.

Index.php:
<?php
/**
* The main template file.
*
* @package WordPress
*/

session_start();

if(isset($_SESSION['pp_homepage_slideshow_style']))
{
$pp_homepage_slideshow_style = $_SESSION['pp_homepage_slideshow_style'];
}
else
{
$pp_homepage_slideshow_style = get_option('pp_homepage_slideshow_style');
}
if(empty($pp_homepage_slideshow_style))
{
$pp_homepage_slideshow_style = 'flow';
}

if($pp_homepage_slideshow_style == 'youtube_video')
{
$_GET['mode'] = 'f';
}


get_header();

$pp_homepage_slideshow_cat = get_option('pp_homepage_slideshow_cat');
$homepage_items = -1;

$args = array( 
'post_type' => 'attachment', 
'numberposts' => $homepage_items, 
'post_status' => null, 
'post_parent' => $pp_homepage_slideshow_cat,
'order' => 'ASC',
'orderby' => 'menu_order',
); 
$all_photo_arr = get_posts( $args );


include (TEMPLATEPATH . "/templates/template-slider-".$pp_homepage_slideshow_style.".php");

if($pp_homepage_slideshow_style != 'fullscreen')
{
get_footer();
}
?>
