What are the important steps in an introduction

I think what is important about an introduction it's that they are telling you how the story is going to be about and how the problem of the story is going to affect (he or she).An introduction can be in different ways of starting it of.They could like,tell you,"there was once a girl or boy called.....''then you could get an idea of what the story is going to be about if it's going to be sad,boring,or interesting.That could get you the attention of the story when you are reading the story with full attention.I think what the main thing of the introduction of the story,is that they give you like ideas and like animating you to read that story that they tell you that the story is going to be cool,by that I mean that it's going to be really interesting and a adventure like you are imagining the story in your head,and you are getting the whole point of the story,and you are like "wow!"This story was really exciting.That's what I think the steps should be when writing an introduction by yourself.
