+Configuration
+=============
+
+Configuration of reltool is done via Erlang key, value elements in the
+`relcool.config` file. There are various configuration elements that
+can appear, each affects the running of the system in specific
+ways. Note that these must be complete Erlang terms terminated by a
+`.`.
+
+Paths
+-----
+
+Paths is a way to add additional code paths (that point to Erlang beam
+files) to the system. These are not used for dependency resolution,
+they are only used as code paths. The main use for this is simply to
+provide a non-resolvable path for additional providers.
+
+the path confuration element looks as follows::
+
+ {paths, [<list of directory paths>]}.
+
+So if we wanted to add `/usr/local/lib` and `/opt/lib` to the code
+paths for the system we could add the following::
+
+ {paths, ["/usr/local/lib", "/opt/lib"]}.
+
+to our configuration.
+
+Providers
+---------
+
+Providers are how the Relcool system can be extended by a user. They
+are basically Erlang modules that implement the `rcl_provider`
+behaviour and are available via a code path. See the section on
+providers for more information.
+
+The `providers` element provides a completely new list of providers,
+replacing any providers that may already exist. The provider element
+is as follows::
+
+ {providers, <list of module names>}.
+
+Lets say I have three providers; `my_custom_assembler`,
+`my_rpm_assembler` and `my_deb_assembler`. I could make these the
+complete list of providers by doing the following in my config::
+
+ {providers, [my_custom_assembler,
+ my_rpm_assembler,
+ my_deb_assembler]}.
+
+Order is important in the providers as they will be executed in the
+order specified.
+
+Add Providers
+-------------
+
+`add_providers` is very similar to `providers` with the exception that
+the listed providers are added to the end of the current list of
+providers rather then replacing the list all together. Add providres
+looks as follows::
+
+
+ {add_providers, <list of module names>}.
+
+Lets take our previous example but only add `my_rpm_assembler` and
+`my_deb_assembler` to the existing list of providers. We do this by
+adding the following::
+
+ {add_providers, [my_rpm_assembler,
+ my_deb_assembler]}.
+
+Releases
+--------
+
+Release configuration is the bread and butter, the blood and bones of
+the Relcool system. It provides the framework for realizing
+dependencies in the system. The release element basically minics the
+standard _Erlang/OTP Release Metadata file format:
+http://www.erlang.org/doc/man/rel.html. There are two main
+differences. The first is that you don't have to specify a complete
+list of applications and you may specify version constraints instead
+of hard versions.
+
+
+{release, {relname, vsn},
+ app goals}
+{release, {relname, vsn},
+{erts, vsn},
+app goals}

+Overview
+========
+
+Relcool is a tool that, given a specification, assembles
+releases. That is it makes an assessment of all of the Erlang/OTP Apps
+available to it and the constraints that you supply as part of your
+configuration and resolves a complete set of OTP Applications and
+thier versions for use in the release. This may be a bit hard to
+understand if you are not familiar with the way version resolutions
+work in package management systems. So lets look at an example.
+
+Lets say that you have the following OTP Applications
+
+* app1-1.2
+ with dependencies::
+ app2
+ app5
+ app6
+* app1-1.3
+ with dependencies::
+ app2
+ app6
+* app2-2.0
+ with dependencies::
+ app6
+* app2-2.1
+ with dependencies::
+ app6
+ app7
+* app3-2.0
+* app4-1.0.0
+* app5-3.0
+* app6-1.0
+ with dependencies::
+ app3
+* app7-2.0
+
+This is the world of OTP Apps your Relcool knows about (basically OTP
+Apps in the Library Directories you have specified). You have set a
+config that looks like the following::
+
+ {release, {awesome_supercool, "1.0"},
+ [{app1, "1.3", '>='},
+ {app2, "2.0", '>'},
+ app3]}
+
+When the Relcool process has run you will end up with a complete release as follows::
+
+ {release, {awesome_supercool, "1.0"},
+ [{app1, "1.3"},
+ {app2, "2.1"},
+ {app3, "2.0"},
+ {app6, "1.0"},
+ {app7, "2.0"}]}
+
+As you can see that is a fully realied view of your direct and
+transative dependencies based on the world that Relcool knows about
+and the constraints that you specified in your configuration.
