add a Menu to my WordPress Theme footer.php?

I’m trying to add a custom footer to my WordPress theme, I upload my static website here and now I trying to make it dynamic, I added my primary menu to WordPress but I don’t know how can I exactly add footer to my wordpress theme?

do I have to make another menu and use it here like

$args= array(
    'theme_location' => 'footer'
wp_nav_menu(); ?>

and then register it in function.php or it has another way?

Thanks in advance!
