Docverter is a collection of a few pieces of software that get used at various times. For example, if you do markdown to docx you'll just be using Pandoc. If you convert to PDF you'll be going through flying saucer. If you go markdown to PDF you'll go through both. MOBI conversions go through Pandoc to get an ePub and then through Calibre to get the mobi.
The point is that you don't have to worry about those pieces, though, since Docverter abstracts over them with a simple API.
