Traditionally, you start from a Word document that gets “placed” in InDesign, and then you start the time consuming process of laying everything out in various styles. However, if you already have a proper digital format such as an epub or clean HTML code, it is simpler and faster to convert the (already marked up) HTML to a Word document with the styles already applied, then import and “map” the styles to a good existing InDesign template such as “Wellred Origins” or “Wellred Chartism”. This is by far the quickest method (as tested on the new Feuerbach book, whose rough draft I put together in a few hours), but it needs to be further tweaked and ideally inspected by an InDesign professional.
This assumes the “Origin” InDesign template, used for smaller books. For larger books, use the “Chartism” template. If basing yourself on a HTML file from MIA or Marxist.com, start from 1) If working from a Word file, start from 4)

in the ‘headings’ section. This should result in a basic layout in accordance with the Wellred template, with 70% of the work now done [could be very wrong here! Am not familiar with the finishing touches in InDesign and what is involved].
