How to configure gunicorn (and make sense out of it)

I have cloned my git repo in :here

/var/www/directoriovirtual/here

then I have created a gunicorn_start file inside: directoriovirtual

the gunicorn_start file reads:

NAME=“django_videos” DIR=/var/www/directoriovirtual/languaget USER=user_videos GROUP=videos WORKERS=3 BIND=unix:/var/www/run/gunicorn.sock DJANGO_SETTINGS_MODULE=tutoriales.settings DJANGO_WSGI_MODULE=tutoriales.wsgi LOG_LEVEL=error

cd $DIR source …/directoriovirtual/bin/activate

export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE export PYTHONPATH=$DIR:$PYTHONPATH

exec …/directoriovirtual/bin/gunicorn ${DJANGO_WSGI_MODULE}:application
–name $NAME
–workers $WORKERS
–user=$USER
–group=$GROUP
–bind=$BIND
–log-level=$LOG_LEVEL
–log-file=-

I have tried to test whether it works but very unsure of what I am doing:

sudo systemctl status gunicorn

and the dreaded answer goes:

Unit gunicorn.service could not be found.

The domain shows nginx is working, now I was trying to add gunicorn and then supervisor but kind of lost at this point.
