before running 'tox -ereleasenotes'.

Documentation
=============
There are a few different kinds of documentation associated with Glance to
which you may want to contribute:
* Configuration
As you read through the sample configuration files in the ``etc`` directory
in the source tree, you may find typographical errors, or grammatical
problems, or text that could use clarification. The Glance team welcomes
your contributions, but please note that the sample configuration files are
generated, not static text. Thus you must modify the source code where the
particular option you're correcting is defined and then re-generate the conf
file using ``tox -e genconfig``.
* Glance's Documentation
The Glance Documentation (what you're reading right now) lives in the source
code tree under ``doc/source``. It consists of information for developers
working on Glance, information for consumers of the OpenStack Images APIs
implemented by Glance, and information for operators deploying Glance. Thus
there's a wide range of documents to which you could contribute.
Small improvements can simply be addressed by a patch, but it's probably a
good idea to first file a bug for larger changes so they can be tracked more
easily (especially if you plan to submit several different patches to address
the shortcoming).
* User Guides
There are several user guides published by the OpenStack Documentation Team.
Please see the README in their code repository for more information:
https://github.com/openstack/openstack-manuals
* OpenStack API Reference
There's a "quick reference" guide to the APIs implemented by Glance:
http://developer.openstack.org/api-ref/image/
The guide is generated from source files in the source code tree under
``api-ref/source``. Corrections in spelling or typographical errors may be
addressed directly by a patch. If you note a divergence between the API
reference and the actual behavior of Glance, please file a bug before
submitting a patch.
Additionally, now that the quick reference guides are being maintained by
each project (rather than a central team), you may note divergences in format
between the Glance guides and those of other teams. For example, some
projects may have adopted an informative new way to display error codes. If
you notice structural improvements that our API reference is missing, please
file a bug. And, of course, we would also welcome your patch implementing
the improvement!
Release Notes
-------------
Release notes are notes available for operators to get an idea what each
project has included and changed during a cycle. They may also include
various warnings and notices.
Generating release notes is done with Reno.
.. code-block:: bash
$ tox -e venv -- reno new <bug-,bp-,whatever>
This will generate a yaml file in ``releasenotes/notes`` that will contain
instructions about how to fill in (or remove) the various sections of
the document. Modify the yaml file as appropriate and include it as
part of your commit.
Commit your note to git (required for reno to pick it up):
.. code-block:: bash
$ git add releasenotes/notes/<note>; git commit
Once the release notes have been committed you can build them by using:
.. code-block:: bash
$ tox -e releasenotes
This will create the HTML files under ``releasenotes/build/html/``.
