WooCommerce is easily integrated with TF themes.
Zip your theme. Unpack it in a local folder.
Duplicate your theme’s page.php file, and name it woocommerce.php.
Edit your page (woocommerce.php)
Open up your newly created woocommerce.php in a text editor, or the editor of your choice.
Replace the loop which usually starts with:
<?php if ( have_posts() ) :
and usually ends with:
<?php endif; ?>
This varies between themes. In TF its several lines. Once you have found it, delete it. In its place, put:
<?php woocommerce_content(); ?>
This will make it use WooCommerce’s loop instead. Save the file. You’re done.
Upload all of the themes folder unpacked, to your WP sites themes folder. Go to Themes and choose the uploaded theme. Should be all hunky dory.
