I'll see if I can figure out how to do that.
Best might be an online app. which could somehow convert a Word file into an HTML file.

It's not really related to Word, but rather, I merely composed the file using Word, with explanations plus crude pics. that might be helpful as a tutorial for beginners to master layers in paint.net.

I've noted confusion online, by at least one other beginner like myself, who didn't grasp layers. Someone like her might have benefitted by such a tutorial, geared to a certain way of thinking.

That's why I composed it (however crude the pictures) except I don't know how to get it to last base.
