[MUSIC] Hey, before we get started, I want to give you this quick disclaimer. Whenever we're going through our labs throughout the course, WebGoat might change the numbering of each individual lab, for instance, cross-site scripting or injection. So just remember what module you're on, and go to the WebGoat section for that module. And you'll see at the top of the page, there will be specific numbers, and the labs are colored either green if you finished them or red if you haven't finished them. And those are the ones you're going to want to focus on.
