    Options:
        -c, --skip-config:  Skip updating JSON configuration files.
        -m, --skip-matrix:  Skip building matrix driver dependency. Video display will default to emulator mode.
        -p, --skip-python:  Skip Python 3 installation. Requires manual Python 3 setup if not already installed.

        -a, --skip-all:     Skip all dependencies and config installation (equivalent to -c -p -m).

        --emulator-only:    Do not install dependencies under sudo. Skips building matrix dependencies (equivalent to -m)
