Adding a line to Buddypress registration page

Hi there,

I’d like to personalise my registration page a bit more.
I want to add a line of text & links at the bottom of the page like this:

What I want

So far what I have achieved is this:

What I get

What I have done so far:

1. I have adjusted the Buddypress registration.php (child theme) and added this line pretty much anywhere to test where it would show up:

<?php
echo "Hello World!";
?>

Result: image number 2.

2.
Created a custom template (copy of page.php) for the registration page and again added this code to see if it would do anything:

<?php
echo "Hello World!";
?>

Result: nothing.

Can anyone tell me where to put what code to get a line of text on the bottom of the buddypress registration page? I’d like to add a link there to terms & conditions.

Thanks in advance everybody!
