Hello I am writting a scientific research paper and have a question concering the prober numbering.

I have the following topics

Table of Contents
Preface
- Decision of Topic
- Acknowledgment
Introduction
- Description of Topic
- Goal of the Paper
- Scope
- ...
Main Part Baiscally consist of all my research and testing, after the conclusion I have still some further points such as
- Further Defining of Topic criticsm, comparing etc
- ...
- Conclusion
- Fruther points

Glossary
Attachement
Progress/ Milestones of writing the paper
Sources

My question is, do I number:

1 Table of Contents
2 Preface
2.1 Decision
2.2 Acknowledgment
3 Introduction
3.1 Description
3.2 ...
4 Main Part Here I first see a problem, what kind of titel is "Main Part" also that would only give me
4.1 ... second degree headings for al my research!
But how do I make the transition from "Introduction" to the "Main Part"?

How to number the rest? How to introduce the conclusion, attachement etc?
Do I number the introduction and preface?

Thanks ever so much!!
Hi! I woner maybe you can also scan some English papers, and you may get your answers more clearly there.

Hi, I have tried that with books but it is difficult to find a book that fits my situation and then there it is always different. I do not know which is the proper way of doing it.
I read some papers before, and it seemed that there were not so much strict rules on writing papers . I'm sorry I don't know the answers very clearly.
