Run ./build-docker-images first, to build docker image(s) containing the tools
Thereafter, run ./build to build the book with the Makefile. The Asciidoc source is in the book directory. Generated output is written within the out/ directory.
Any arguments to the ./build command are passed to make in the Docker container. E.g. ./build html will build only the HTML output, and ./build pdf will build only the PDF output.
To build automatically in the background as you save files, run ./build-continuously. This script also passes arguments through to make. E.g. ./build-continually html will rebuild the HTML whenever you save changes to the source.
