Hello,

It would be nice if you can elaborate your question a little. As far as I assume you are asking about on how to write an introduction and need for the project ? Introduction of the topic includes the basic information about the topic like its meaning, history etc. Talking about the need for the project then it talks about the scope of the project, what it will help you in the future etc.

If not, please specify the question and then I will be able to help you better.
