add short explanation how it works to README.md

[erichstuder]

Summary

I found a short but very informative explanation on how it works.
This helped me a lot as a newbie.

About the questions at the end:
It is NOT my own work. And it is copied from Stack Overflow.
I think as I have added a link to the source and the author it could be acceptable.

Anyway, it would be great to have an explanation like this in the README.md.

Details

Add a chapter to README.md that explains how it works.

Motivation and Context

Faster understanding of the tool.

How Has This Been Tested?

N/A

Types of changes

• Bug fix (non-breaking change which fixes an issue).
• New feature (non-breaking change which adds functionality).
• Breaking change (fix or feature that would cause existing functionality to not work as expected).

Checklist:

• [ NO ] It is my own work, its copyright is implicitly assigned to the project and no substantial part of it has been copied from other sources (including Stack Overflow). In rare occasions this is acceptable, like in CMake modules where the original copyright information should be kept.
• I'm using the same code standards as the existing code (indentation, spacing, variable naming, ...).
• [n/a] I've added tests for my code.
• [n/a] I have verified whether my change requires changes to the documentation
• My change either requires no documentation change or I've updated the documentation accordingly.
• [n/a, only one commit] My branch has been rebased to main, keeping only relevant commits.

Thanks for contributing. It looks like a good addition.
I am not sure bout the licensing as stack-overflow is CC BY-SA 4.0 and we have a MIT license. On the other hand, it is not in the production code.

Is it possible to have the author of the text hand in the PR?
Or otherwise only add a link?

@paoloambrosio used to be a maintainer here so I wouldn't worry about it too much
