In addition to watching this video, you may find it helpful to rerun the interactive tour of your dashboard, which you should have received when you logged in to Moodle for the very first time. 
You can rerun it at any time by scrolling to the very bottom of your dashboard page (Moodle Home page), to the very bottom of the green footer, and click "Reset user tour on this page".
