Can you tell us what you thought it might have been?
I knew it was the address of the gitlab server, but since the docs’ example
gitlab.example.com uses a subdomain, I thought I might have to use one too, like my username or something. As an inexperienced user, I was configuring my account without being conscious that you could host your own gitlab instance.
The doc is clear, but maybe specifying that the
instance url for gitlab’s instance is simply
gitlab.com would be clearer for new users.
In that case I can see why the text is slightly confusing. I have created
to have the page improved a bit.
