Sending mail at startup for a new user

hello, i am a new user so, sorry for disturbing the forum.
I try to send a mail at the startup of hass.
I already configured the configuration part, but now, I think I have problem with the automation part.
Here is the automation that I copied from other web site.

t- id: "Hass Startup Notification"
  alias: 'Hass Startup Notification'
    - platform: homeassistant
      event: homeassistant.restart
      title: "Warning"
      message: "Hass restarted"ype or paste code here

is that something wrong ?
The error message is:
Invalid config for [automation]: not a valid value for dictionary value @ data[‘trigger’][0][‘event’]. Got None. (See /config/configuration.yaml, line 13). Please check the docs at

The line 13 of the config file is just the link for the automation file.

Is that possible for somebody to explain me the problem ?
Many thanks in advance.
Best regards

No need to apologize. That’s what the forum is for. :slight_smile:

See the documentation, especially for the homeassistant trigger:

thanks a lot !
