[ARCHIVED] enable help center for end-users

Hi,

i've already used the guide about help center but it tells to:

To enable help center in setup mode

1. Sign in to Zendesk Support as the account owner.
   Note: You must be the account owner to enable the help center.
2. Click the Zendesk Products icon () in the top bar, then select Guide.
3. In the page that appears, click Get started

when i click in guide it move me in "subscription" not in guide 

or going into https://support.zendesk.com/hc/en-us clicking help center i don't see the settings.

Could someone explain me what should i do?

thank you so much!
