Need Quick Help With Product Category Page

For Woocommerce product categories, use

<?php if ( is_product_category() ) {

 echo '<div id="prodcatdesc">';

  if ( is_product_category( 'shirts' ) ) {
    echo 'Hi! Take a look at our sweet tshirts below.';

  } elseif ( is_product_category( 'games' ) ) {

    echo 'Hi! Hungry for some gaming?';
  } else {

    echo 'Hi! Check our our products below.';

    echo '</div>';
  }

} ; ?>

Or, for just one,

<?php 

     if ( is_product_category( 'shirts' ) ) {

        echo '<div id="prodcatdesc">';
        echo 'Hi! Take a look at our sweet tshirts below.';
        echo '</div>';
        } ;

 ?>
