Help needed with wordpress "Ultimate tag warrior plugin" Very important

I want to install "Ultimate tag warrior plugin" to my wordpress ,and I found the instructions,in that thay have mentioned that
* Add this code to your template theme (You have to add it into ‘the loop’ in your theme’s index.php file and probably in your single.php and home.php if your theme uses them.):

<p>Tags: <div class=”utwtags”>
<?php UTW_ShowTagsCurrentPost(“commanlist”) ?>
</div></p>


* You will need to click on the code (which is actually a picture), and a new window will pop up that you can copy the code from.
* Paste the code in right after the below code that makes the content for the pages; it looks like this: (Your theme might have a variation of this but it should still say ‘the_content’)

<?php the_content ( ) ; ?>

* Save the file(s) and upload if necessary. Using the code I gave you, your tags will end up looking like this (eventually):


What do they mean and where should i edit my theme to add this...Please state clearly
