+$Id: $
+
+This document describes how to setup a Bcfg2 repository from scratch.
+
+1. /etc/bcfg2.conf
+
+This file tells Bcfg2Server important bootstrapping information about
+where its repository is, and which configuration structuring agents
+and generators should be used to build client
+configurations. The list of structures and generators are comma
+delimited and must be importable by python from the
+Bcfg2.Server.(Generators|Structures) hierarchy (respectively). All
+options currently are in the [server] section.
+
+repository: top level of configuration file repository
+structures: comma delimited list of structuring agents to use.
+generators: comma delimited list of generators to use.
+metadata: path to the directory where metadata.xml (the client
+ metadata setup) resides.
+
+2. metadata/metadata.xml
+
+This file defines metadata constructs for all known systems. This file
+contains two types of declarations: one for clients, including an
+attribute for client image, and client nodes for class membership and
+attributes. See the example file for more info. This file doesn't
+need to be exhaustively written: bcfg2 will soon support defaults (to
+support environments where machines are frequently added) and default
+profiles.
+
+3. The repository
+
+Structuring agents and generators are responsible for contructing
+client configurations. All of these currently use FAM to coherently
+cache files on disk, with notifications upon file changes. The
+repository contains a directory for each of these; which is structured
+according to the needs of that generator/structure. \ No newline at end of file

+1. Client Metadata
+
+Clients are differentiated in terms of several types of
+metadata. These types (from least to most specific) are:
+
+- image : the binary compatibility domain of the machine (like
+ debian-3.1 or redhat-7.3)
+- classes : a host can belong to multiple classes. Classes are used to
+ derive the set of software to install on a particular client.
+- bundles: bundles are a sets of related bits of
+ configuration. Generally, each bundle provides some piece of
+ discrete functionality.
+- attributes : attributes can be used to further differentiate
+ bundles, or client configurations and are bundle scoped. A host
+ may have the webserver.ssl attribute if it is supposed to provide
+ ssl/https services in addition to normal port 80 http service.
+- hostname : this is kind of obvious \ No newline at end of file
