Display mycred user rank

Hey there!
Just installed mycred plugin and I am trying to display user rank in the frontend or specifically on the pricing page, I am a newbie so I dont know where to put the code I need. Please show me where I should put which code. I found this code:

// Points current_user backend
<?php echo mycred_get_users_cred( ); ?>

// Rank current_user backend
<?php echo mycred_get_my_rank(); ?>

// Points front-end
<?php echo mycred_get_users_cred(get_the_author_meta('ID')); ?>

// Rank front-enbd
<?php echo mycred_get_users_rank( get_the_author_meta('ID') ); ?>

on this page and more code here, but I still do not know what to do, please assist.
Thanks,
Mwale
