+Description
+===========
+
+The debconf container build script uses debconf(1) to automatically build a
+Debian based container.
+
+Scope
+-----
+
+Note that this container build script can do a few things more than just
+automatically debootstrap based on a preseed file. It also allows you to set a
+root password, configure the network, install certain packages and execute
+hooks.
+
+But: this is *not* a replacement for a configuration management system (like
+ansible, puppet, etc.). The intenion of this script is to build the initial
+container to that extend that a configuration management system can take over.
+
+As an analogy, think of debian-installer: d-i sets up your system to make it
+ready to boot and connect to the network. Everything after that is out of scope.
+Same goes for this script.
+
+Functions
+---------
+
+This script performs the following configuration on top of a Debian based
+system:
+
+  * network
+  * root password
+  * apt repositories
+  * \.\.\.
+
+Modes
+-----
+
+This container build script can be used under two different names: debian and
+progress-linux.
+
+Alternative, calling it under the debconf name is equal to the debian mode.
+
+Preseeding
+----------
+
+Hierarchy of Preseed Files:
+
+  * The debconf script can be fully preseeded. Such preseed files can include
+    one or more preseed files themselfs (currently, only one layer of includes
+    is supported, no nested or recursive includes).
+
+  * The general rule of 'the later preseed file overwrites the earlier' applies.
+    The debconf script reads the main preseed file (specified either on command
+    line or by debconf selection/input dialog) after any included preseed files
+    in there.
+
+  * That means that debconf values after the include statement in the main
+    preseed file can overwrite any values specified in the included preseed
+    files.
+
+Options
+=======
+
+The following script options are available:
+
+-n, --name='NAME':
+  Specify container name.
+
+-p, --preseed-file='FILE':
+  Specify the preseed file.
+
+Examples
+========
+
+Build a Debian based container:
+
+  sudo container build -s debian -n debian.example.net
+
+Build a Progress Linux container:
+
+  sudo container build -s progress-linux -n progress.example.net
