Word and Scrivener

My daughters are working on an anthology which they hope to publish, most likely Amazon. This is not in my wheelhouse. They tell me that using Word to publish eBooks doesn't yield satisfactory results. That it results in a bad looking book.

I've no idea why, I love working with Word. It does everything and more than I need. More than that I've seen some phenomenal Word documents.

But in this case publishing ebooks, Word won't cut it. Instead, the application of choice is something called Scrivener. Tonight, we downloaded Scrivener. It isn't anything simple like Notepad. So, what I'd like to know is how do you take a Word document and convert/import it into Scrivener?
