The documentation is built with Golda (a fork of Hugo).
You can find some prebuilt binaries on their releases page. If your environment is not covered by those you can build it yourself (Standard edition is sufficient).
Once you have a binary, it's a good idea to add it to your PATH so you can call it from anywhere.
