Subject Re: a couple of comments on the airflow 2.0 installation docs
Date Mon, 11 Jan 2021 08:39:27 GMT

I just checked the docs again and I found that the [Quick Start Guide]( does
provide the user-creation command. I'll see if I can update the
installation instructions to add it there after "Initializing database".

take care!
