After going over the documentation for installing Airflow, and using Postgres as a backend, I am really confused.
There is no guide or step by step installation manual, just some random things, ideas and fragments of memory that someone splat down on a web page. --- I am led to believe that I need to configure things with postgres before running `airflow initdb`, but that is not clear in the documentation. Do I create a role/user first before using Airflow? and specify that somewhere in a config file before running 'airflow initdb' -- Also the instructions jump right in talking about something called 'sql_alchemy' as if I should know what that is, but I don't. In addition it says: If you decide to use *Postgres*, we recommend using the psycopg2 driver , and again, no instructions there as to what that means. --- I am more than willing to help the project write clear, concise documentation and communicate with others, as it seems no one on the team has developed this skill set, that can be put to use to help others get this installed. If someone could Jesus please take just five minutes and document this so I do not waste 3-4 hours doing research, subscribing to user lists and being misled by the drive by geniuses that respond on Stackoverflow it would be greatly appreciated.
