A Newbie….

hi, i just bought a site and don’t really know what to do….

I have already set the host and all the other stuff, should i delete all the directories that came with the host or should i keep them?

How do you change a template?

And what does this mean?

<?php
// ** MySQL settings ** //
define(‘DB_NAME’, ‘RER’); // The name of the database
define(‘DB_USER’, ‘RER’); // Your MySQL username
define(‘DB_PASSWORD’, ‘RER’); // …and password
define(‘DB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value

What should i put as the name of the database, MySQL username and password? Any examples please? I have already checked some and the video, but I still don’t get it…..

PLEASE…….. IM SO CONFUSED RIGHT NOW……
Thx for taking your time and reading this post, Hopefully someone can help me, Thx
