I've just installed SilverStripe. I love the way the page adding/editing works. What I'm trying to get a handle on now is how to assign new themes. I downloaded one from silverstripe.com and uploaded it to the themes folder, but for the life of my I cannot fine the mysite/_config.php file. When I open the mysite/ folder, I don't see any files at all - just four folders: code, css, images, and javascript. This seems so elementary. What am I missing?
