The only thing that will be new for you is the USB stick with TAILS inside. You hardly need commands, you just boot up and click anything you want. Like a Firefox with TOR add-ons, a TOR browser itself, and so on. You can also download packages for things like Krita, LibreOffice, Latex Editor, VLC, and such. You don't need much more anyways and you will not leave any data left for Facebook, Google or Amazon.
