Depending on how you want to create the tutorial line, an easy way would be to put some branch nodes to block/enable some controller inputs as progress and at the end give a Load Level to leave tutorial. You can also use what the answer indicated above and save your progress so you don’t have to repeat the tutorial. Something more complex would probably depend on some information, like what you intend to do and even the language you are going to use.
Some games prefer to leave control free and just set goals with information about what to do. For example, do you want to teach walking? Just indicate how he walks and put an “end point” for the player to walk to the point. So you could do that and just save the information and load another level. : )
