Woocommerce – PHP array

I’m building a WordPress site and integrating the Woocommerce plugin. My PHP knowledge is minimal, but am slowly learning.

I need to output an unordered list of the store categories which will include the featured image and the category name.

The Woocommerce documentation has the following array, but I’m not sure what to do with it:

array(
  'number' => 'null',
  'orderby' => 'name',
  'order' => 'ASC',
  'columns' => '4',
  'hide_empty' => '1',
  'parent' => '',
  'ids' => ''
)

Any advice/help would be much appreciated.
Thanks!
