Usage:

[-b | -d] [-p PORT] [-s] [-t DIR] [-u]

-b      - Build the build & dev images instead of pulling from the registry
-d      - Build the dev image instead of pulling from the registry
-p PORT - Port to listen on
-s      - Skip pulling build/dev images
-t DIR  - Use DIR to for the theme, to develop the theme at the same time
-w DIR - Use DIR to for the website, to set enableRobotsTXT to false locally in order to scan for broken links on local build
-u      - Upload/push the build image after building
