How do i make the hass daemon file?

I have a Synology DS214 play nas.

I followed the link https://home-assistant.io/docs/installation/synology/
I used Terminal as i have an Apple Mini and after i finally got access i got to the moment that i must create the hass daemon file. (my user for the Home Assistant is assistant i tried to make it homeassistant but my synology said it was reserved for the synology system I put al the text in my terminal, but nothing happened,

#!/bin/sh

Package

PACKAGE=“homeassistant”
DNAME=“Home Assistant”

Others

USER=“assistant”
PYTHON_DIR="/volume1/@appstore/py3k/usr/local/bin"
PYTHON="$PYTHON_DIR/python3"
HASS="$PYTHON_DIR/hass"
