 mkdir -p "$PWD/doc/_build/"
 docker run -it --rm \
            --user "$(id -u):$(id -g)" \
            -v "$PWD/:/data-in/:ro" \
            -v "$PWD/doc/_build/:/data-out/" \
            doc.flashrom.org

Live web server:
 docker run -it --rm \
            --net=host -v "$PWD/:/data-in/:ro" \
            doc.flashrom.org livehtml
