I self published a book of my poetry on Kindle Direct publishing 5 years ago see http://a.co/iw4r1jq
I also used lulu to make a physical copy. For lulu I think I used Microsoft word and for kindle you could just make a HTML document to be published . The tooling in this article is great but as other people have pointed out marketing your book is more important. The article should be titled how to typeset a novel in 2017.
