Need help with integrating hype it! Button

Hallo,

I have a blog under http://www.frank-hamm-webdesign.de

I want to integrate a hype it! Button in every posting.

Therefore I downloaded the WordPress plugin from http://hype.yeebase.com/tools/

I placed it in the plugin folder, activeted it, set the tags for publishing and them I am at the point where my problem is .

The Installation guide says

Include the following php-function in your theme/templates using this snippet: getButton(get_permalink(),get_the_tags()); ?>

or (maybe the better way)

<?php if ( is_object($hypeIt) ) : ?>
<?php echo $hypeIt->getButton(get_permalink(),get_the_tags()); ?>
<?php endif; ?>

So my Question is where do I have to include this to have the button in every posting?

Thanks in advance
