How do I enable full self driving on a Tesla

Just a quick video on how to turn on full self driving in a Tesla for the newer stockless Teslas how you engage it I’m not sure if you just do the navigation and hit a button. Somebody wants to fill me in there. That would be great on these older models. She just pulled the stick like you’d normally engage auto pilot but once you have a destination enable, then it will go to that destination not the only way it full self drives if it has somewhere to go then it will do it. If not, it just does regular auto pilot.
