This is a boilerplate project for multivolume documentation using Hugo and the hugo-material-docs theme.
$ git clone --recursive https://github.com/lambdafu/hugo-material-book
$ cd hugo-material-book
$ hugo server
For PDF generation to work, you need Pandoc and a reasonably complete Texlive environment.
$ make
You also need to limit yourself to the common subset of Hugo's blackfire markdown and Pandoc markdown. A couple of extensions are available and converted appropriately in the Python script.
