Actually, it depends on the age level of your new employee. If there are many young people, you need to get involved first, including some interactions, including making the introduction more vivid and impressive, and so on. In the training of newcomers, you can't read according to what you have prepared. Most people would prefer to listen to actual cases. Of course, you can think about this so-called actual case yourself. Otherwise, newcomers are already very stiff in a new environment. If you come back with very rigid things, it is easy to cause some negative things!
