Can MarginNote read Kindle?

Just came across MarginNote a day or two ago and am not a user (yet!) but wondert what formats it can read. PDFs, of course, and apparently ePub too. I need to read and annotate both of those but I’ve also accumulated well over 2,000 Kindle books and I don’t see anything here that indicates I could use MarginNote to read and annotate those. Is it possible?

Documents (PDFs, ePub, Kindle, Mobi, etc.) that have DRM are not able to be read in Marginnote
