 PostgreSQL is the self proclaimed "world's most advanced" open source relational
 database. This ansible role can deploy and configure postgresql.
 
-By default, the role configures the remote's effective ansible user with
-peer authentication for the (postgresql) role `postgres` on all databases (with all grants).
-
-## Required configuration
-
-Set `postgresql_superuser_password` to your superusers desired password.
-
-## Optional configuration
-
-Set `postgresql_major_version` to your desired postgresql major version,
-for supported major versions see [`defaults/main/main.yml`](defaults/main/main.yml#L6).
-
-This role can be executed multiple times with different
-`postgresql_major_version` values to provide new database versions for up-to-
-date applications and older versions for software which does not yet support
-them. Container name and host mounts encode the major version to prevent
-accidental usage of the 'wrong' `PGDATA` directory.
-
 ## Requirements
 
 - `psycopg2` (pip) package
