[Plugin: Posts for Page] Where do I place the script

I activated the plugin. I can’t understand the next step. the FAQ says:

Some of our clients wanted to output some posts in a specific page without fiddling with templates.

This plugin goes well with our Simple Page Specific Sidebars plugin, and gives you more granular control of sidebars on specific categories, post-types, etc.

How do I change the output template
Simply copy the posts_loop_template.php to your theme directory and make changes as necessary.

You can even rename it – but make sure to indicate that in the shortcode using the template=’template_name.php’.

What do I need to edit and where do I place the script on the page I want it to be posted? My site is http://roundhousetalk.com I’m lost. I want to place news post i get with “Press This” . The posts show up in my “Past Articles” at http://roundhousetalk.com/2012/10/
