I found [bookdown](https://bookdown.org/) and I had some prior experience with R so I decided to try it out. Using bookdown, it turned out I didn't have to use any R at all. I used [Rstudio's bookdown-demo repo](https://github.com/rstudio/bookdown-demo) to get started right away. I converted my txt into Rmd files in Rstudio and used the console to build html and pdf files of the book. The html files use a git-book format. LaTeX is necessary for the pdf generation, and can be used in the .Rmd files but I didn't need this ability for this text.
