+Basic Configuration
+===================
+
+The ``distil.conf`` configuration file is an
+`INI file format <https://en.wikipedia.org/wiki/INI_file>`_.
+
+This file is located in ``/etc/distil``. If there is a file ``distil.conf`` in
+``~/.distil`` directory, it is used instead of the one in ``/etc/distil``
+directory. When you manually install the Rating service, you must generate
+the distil.conf file using the config samples generator located inside distil
+installation directory and customize it according to your preferences.
+
+To generate the sample configuration file ``distil/etc/distil.conf.sample``:
+
+.. code-block:: console
+
+   # pip install tox
+   $ cd distil
+   $ tox -e genconfig
+
+Where :samp:`{distil}` is your Rating service installation directory.
+
+Then copy Rating service configuration sample to the directory ``/etc/distil``:
+
+.. code-block:: console
+
+   # cp etc/distil.conf.sample /etc/distil/distil.conf
+
+For a list of configuration options, see the tables in this guide.
+
+.. important::
+
+   Do not specify quotes around configuration options.

+
+====================================
+Welcome to the Distil Documentation!
+====================================
+
+
+Project scope
+=============
+
+Distil is a service to provide easy interactions with ERP systems, by exposing
+a configurable set of collection tools and transformers to make usable billing
+data out of Ceilometer entries.
+
+Distil provides a rest api to integrate with arbitrary ERP systems, and returns
+quotations/invoices as json. What the ranges are, and how Ceilometer data is
+aggregated is intended to be configurable, and defined in the configuration
+file.
+
+The Distil data store will prevent overlapping bills for a given tenant and
+resource ever being stored, while still allowing for regeneration of a given
+invoices.
+
+Design principles
+=================
+
+Distil, as with all OpenStack projects, is designed with the following
+guidelines in mind:
+
+* **Component-based architecture.** Quickly add new behaviors
+* **Highly available and scalable.** Scale to very serious workloads
+* **Fault tolerant.** Isolated processes avoid cascading failures
+* **Recoverable.** Failures should be easy to diagnose, debug, and rectify
+* **Open standards.** Be a reference implementation for a community-driven
+
