You will need Ruby installed. If you're running this on windows, you can try https://rubyinstaller.org/downloads/ Then, once you have ruby installed, you will need Jekyll (A ruby gem) installed.
So just
gem install jekyll
Finally, you will need the FHIR IG Publisher. It's available on: https://github.com/HL7/fhir-ig-publisher
And you're ready to go.
java -jar publisher.jar -ini ig.ini
And check the output folder.
