How to use woocommerce hooks?

Question

WordPress

Perhaps a stupid question, but still, for understanding. For example, there is a woocommerce_cart_is_empty hook. That is, it should be activated provided that the basket is empty.
How to activate it and where to change it. For example, what if the cart is empty, then the output is an inscription? Thanks in advance.
