Stuck installing

I am arrived here with appdaemon installation, after modifiyng the conf file I receive

pi@hassbian:~/appdaemon_dashboard/appdaemon $ python3 -m appdaemon.appdaemon -c /home/pi/appdaemon_dashboard/appdaemon/conf
Traceback (most recent call last):
File “/usr/lib/python3.4/runpy.py”, line 170, in _run_module_as_main
main”, mod_spec)
File “/usr/lib/python3.4/runpy.py”, line 85, in _run_code
exec(code, run_globals)
File “/home/pi/appdaemon_dashboard/appdaemon/appdaemon/appdaemon.py”, line 1807, in
main()
File “/home/pi/appdaemon_dashboard/appdaemon/appdaemon/appdaemon.py”, line 1570, in main
conf.dash_url = config[‘HADashboard’].get(“dash_url”)
KeyError: ‘HADashboard’
pi@hassbian:~/appdaemon_dashboard/appdaemon $
