Woocommerce attributes?

Question

WooCommerce

Hey! There is an attribute in Woocommerce.
I take it out like this

<?php global $product; echo $product->get_attribute('color');?>

But attributes are displayed all and just a list of all
And how to display them in a checkbox, and each attribute term in its own? It's supposed to be a cycle, but I can't get the gist of it.
