Sorry, but that's not particularly useful. You have not provided any info about your system or other details like how you access the tutorial and for that matter the Internet in general. As a start, check the menu's Help --> Show Welcome screen option if that's what you're looking for. You can also access the online help directly via a browser, of course. Otherwise more info is required.
