Social Connect - I need help

[wikio]

Hi guys, I'm new.
I've just bought the Social Conncet plugin.
I got the Facebook App ID and Facebook App Secret, then I enabled and saved the changes.
Next in the help section I saw that I need to add this code
<?php osc_run_hook('sc_buttons'); ?>
inside user-login.php, user-register.php

My question is:
Exactly where do I need to add the code? In which line?

I don't want to make a mistake.

Thanks

You can add it where you want really. I put mine a line below the submit button for login/register.
