    Run Rails on docker using a single command by Petar <Shannarra> Angelov (https://github.com/Shannarra/)

    By default this script will own all of the project's files to your user, create an .env file and
    setup the database with basic models' data. 

    This does NOT include authorization with Devise, for that see --device.

    Commands:
    -d, --devise [NAME]         => setup the application using Devise with given NAME 
    -r, --run                   => start the container up when the setup has finished.
    -h, --help                  => display this message
