     * `$(pwd)`: runs `pwd` ("print working directory") and puts it as part of the string.
 * `/start-reload.sh`: adding something (like `/start-reload.sh`) at the end of the command, replaces the default "command" with this one. In this case, it replaces the default (`/start.sh`) with the development alternative `/start-reload.sh`.
