* Automatic Dockerfile update by release process

We've seen multiple users thinking that simple creation of two containers
is enough, whereas this isn't the case: at the very least, the deprecated
`--link` docker option must be used, but more compliant is the use of
custom networks and bridges. Docker-compose sets all that up automatically,
so don't suggest going without docker-compose is simpler.

 The quickest way to get this image up and running is by using the

-# How to use this image
 
-## Start a postgres instance
+## Manual installation
 
-```plain
- $ docker run -d --name postgres \
-              -e POSTGRES_PASSWORD=mysecretpassword \
-              postgres:latest

-BEWARE: The command above creates a container with the database data stored
-*inside* the container. Upon removal of the container, the database data will
-be removed too!
-
-To prevent destruction of the database data upon replacement of the container,
-please use these commands instead:
-
-```plain
- $ docker volume create dbdata
- $ docker run -d --name postgres \
-              -e POSTGRES_PASSWORD=mysecretpassword \
-              -e PGDATA=/var/lib/postgresql/data/pgdata \
-              -v dbdata:/var/lib/postgresql/data \
-              postgres:latest

+This section assumes availability of a PostgreSQL server to attach to the
+LedgerSMB image as the database server.
 
 ## Start LedgerSMB

+              -e POSTGRES_HOST=<ip/hostname> ledgersmb/ledgersmb:latest
 ```
 
 This command maps port 5762 of your container to port 5762 in your host. The
