So I'm just learning how to use WordPress, I know Joomla pretty well so it's not my first time at CMS. I'm confused how I might go about editing the template? I see there's a place in the WP admin panel where you can go edit the CSS and some pages of HTML but would that be the proper way to go back about making changes to the template? Just so I know that where I'm starting is the correct place. I'm looking to change around the whole template not just a few things here and there.
