I'm building a site offline (using MAMP) with the Hatch theme.
I'd like to use category pages and am trying to find a way to get the category description to appear above the post thumbnails on the category index page (i.e. site/category/xxxx)
I've found the command <?php echo category_description( $category_id ); ?> on the wordpress reference site but I can't work out where to put this, and on which page template to make it work.
Any bright ideas?
