-## Further Configuration
-
-This further configuration is not required for Google authentication to function
-but it is strongly recommended. Taking these steps will increase usability for
-users by providing a little more recognition and branding.
-
-At this point, when users first try to authenticate to your GitLab installation
-with Google they will see a generic application name on the prompt screen. The
-prompt informs the user that "Project Default Service Account" would like to
-access their account. "Project Default Service Account" isn't very recognizable
-and may confuse or cause users to be concerned. This is easily changeable:
-
-1. Select 'Consent screen' in the left menu. (See steps 1, 4 and 5 above for
-   instructions on how to get here if you closed your window).
-1. Scroll down until you find "Product Name". Change the product name to
-   something more descriptive.
-1. Add any additional information as you wish - homepage, logo, privacy policy,
-   etc. None of this is required, but it may help your users.
