+===============================
+OpenStack Vitrage Specifications
+===============================
+
+This git repository is used to hold approved design specifications for additions
+to the Vitrage project. Reviews of the specs are done in gerrit, using a similar
+workflow to how we review and merge changes to the code itself.
+
+The layout of this repository is::
+
+  specs/<release>/
+
+Where there are two sub-directories:
+
+  specs/<release>/approved: specifications approved but not yet implemented
+  specs/<release>/implemented: implemented specifications
+
+This directory structure allows you to see what we thought about doing,
+decided to do, and actually got done. Users interested in functionality in a
+given release should only refer to the ``implemented`` directory.
+
+You can find an example spec in `doc/source/specs/template.rst`.
+
+Specifications are proposed for a given release by adding them to the
+`specs/<release>` directory and posting it for review.  The implementation
+status of a blueprint for a given release can be found by looking at the
+blueprint in launchpad.  Not all approved blueprints will get fully implemented.
+
+Specifications have to be re-proposed for every release.  The review may be
+quick, but even if something was previously approved, it should be re-reviewed
+to make sure it still makes sense as written.
+
+Prior to the Kilo development cycle this repository was not used for
+spec reviews. Reviews prior to Juno were completed entirely through
+Launchpad blueprints::
+
+  http://blueprints.launchpad.net/vitrage
+
+Starting from the Kilo-1 development milestone Vitrage performs the pilot of
+the specs repos approach.
+
+Please note, Launchpad blueprints are still used for tracking the
+current status of blueprints. For more information, see::
+
+  https://wiki.openstack.org/wiki/Blueprints
+
+For more information about working with gerrit, see::
+
+  http://docs.openstack.org/infra/manual/developers.html#development-workflow
+
+To validate that the specification is syntactically correct (i.e. get more
+confidence in the Jenkins result), please execute the following command::
+
+  $ tox
+
+After running ``tox``, the documentation will be available for viewing in HTML
+format in the ``doc/build/`` directory.

+==========================================
+Example Spec - The title of your blueprint
+==========================================
+
+Include the URL of your launchpad blueprint:
+
+https://blueprints.launchpad.net/vitrage/+spec/example
+
+Introduction paragraph -- why are we doing anything? A single paragraph of
+prose that operators can understand. The title and this first paragraph
+should be used as the subject line and body of the commit message
+respectively.
+
+Some notes about using this template:
+
+* Your spec should be in ReSTructured text, like this template.
+
+* Please wrap text at 79 columns.
+
+* The filename in the git repository should match the launchpad URL, for
+  example a URL of: https://blueprints.launchpad.net/vitrage/+spec/awesome-thing
+  should be named awesome-thing.rst
+
+* Please do not delete any of the sections in this template.  If you have
+  nothing to say for a whole section, just write: None
+
+* For help with syntax, see http://sphinx-doc.org/rest.html
+
+* To test out your formatting, build the docs using tox, or see:
+  http://rst.ninjs.org
+
+* If you would like to provide a diagram with your spec, ascii diagrams are
+  required.  http://asciiflow.com/ is a very nice tool to assist with making
+  ascii diagrams.  The reason for this is that the tool used to review specs is
+  based purely on plain text.  Plain text will allow review to proceed without
+  having to look at additional files which can not be viewed in gerrit.  It
+  will also allow inline feedback on the diagram itself.
+
+* If your specification proposes any changes to the Vitrage REST API such
+  as changing parameters which can be returned or accepted, or even
+  the semantics of what happens when a client calls into the API, then
+  you should add the APIImpact flag to the commit message. Specifications with
+  the APIImpact flag can be found with the following query:
+
+  https://review.openstack.org/#/q/status:open+project:openstack/vitrage-specs+message:apiimpact,n,z
+
+Problem description
+===================
+
+A detailed description of the problem:
+
+* For a new feature this might be use cases. Ensure you are clear about the
+  actors in each use case: End User vs Deployer
+
+* For a major reworking of something existing it would describe the
+  problems in that feature that are being addressed.
+
+
+Proposed change
+===============
+
+Here is where you cover the change you propose to make in detail. How do you
+propose to solve this problem?
+
+If this is one part of a larger effort make it clear where this piece ends. In
+other words, what's the scope of this effort?
+
+Alternatives
+------------
+
+What other ways could we do this thing? Why aren't we using those? This doesn't
+have to be a full literature review, but it should demonstrate that thought has
+been put into why the proposed solution is an appropriate one.
+
+Data model impact
+-----------------
+
+Changes which require modifications to the data model often have a wider impact
+on the system.  The community often has strong opinions on how the data model
+should be evolved, from both a functional and performance perspective. It is
+therefore important to capture and gain agreement as early as possible on any
+proposed changes to the data model.
+
+Questions which need to be addressed by this section include:
+
+* What new data objects and/or database schema changes is this going to
+  require?
+
+* What database migrations will accompany this change.
+
+* How will the initial set of new data objects be generated, for example if you
+  need to take into account existing instances, or modify other existing data
+  describe how that will work.
+
+REST API impact
+---------------
+
+Each API method which is either added or changed should have the following
+
+* Specification for the method
+
+  * A description of what the method does suitable for use in
+    user documentation
+
+  * Method type (POST/PUT/GET/DELETE)
+
+  * Normal http response code(s)
+
+  * Expected error http response code(s)
+
+    * A description for each possible error code should be included
+      describing semantic errors which can cause it such as
+      inconsistent parameters supplied to the method, or when an
+      instance is not in an appropriate state for the request to
+      succeed. Errors caused by syntactic problems covered by the JSON
+      schema definition do not need to be included.
+
+  * URL for the resource
+
+  * Parameters which can be passed via the url
+
+* Example use case including typical API samples for both data supplied
+  by the caller and the response
+
+* Discuss any policy changes, and discuss what things a deployer needs to
+  think about when defining their policy.
+
+Versioning impact
+-----------------
+
+Discuss how your change affects versioning and backward compatibility:
+
+* Can it break any existing DSL code even in theory?
+
+* If you make changes to Vitrage package please state how the version number
+  should be incremented?
+
+* Does your change require newer version of external or internal component?
+
+* How to keep backward compatibility with code and consumers that were
+  available prior to your change?
+
+Other end user impact
+---------------------
+
+Aside from the API, are there other ways a user will interact with this
+feature?
+
+* What does the user interface there look like?
+
+Deployer impact
+---------------
+
+Discuss things that will affect how you deploy and configure OpenStack
+that have not already been mentioned, such as:
+
+* What config options are being added? Should they be more generic than
+  proposed (for example a flag that other hypervisor drivers might want to
+  implement as well)? Are the default values ones which will work well in
+  real deployments?
+
+* Is this a change that takes immediate effect after its merged, or is it
+  something that has to be explicitly enabled?
+
+* If this change is a new binary, how would it be deployed?
+
+* Please state anything that those doing continuous deployment, or those
+  upgrading from the previous release, need to be aware of. Also describe
+  any plans to deprecate configuration values or features.  For example, if we
+  change the directory name that instances are stored in, how do we handle
+  instance directories created before the change landed?  Do we move them?  Do
+  we have a special case in the code? Do we assume that the operator will
+  recreate all the instances in their cloud?
+
+Developer impact
+----------------
+
+Discuss things that will affect other developers working on OpenStack,
+such as:
+
+* If the blueprint proposes a change to the driver API, discussion of how
+  other hypervisors would implement the feature is required.
+
+Horizon impact
+--------------
+
+Does it require changes to the horizon? If so, changes
+should be described well. If it's about complex changes than probably a
+separate blueprint / spec should be created for it.
+
+
+Implementation
+==============
+
+Assignee(s)
+-----------
+
+Who is leading the writing of the code? Or is this a blueprint where you're
+throwing it out there to see who picks it up?
+
+If more than one person is working on the implementation, please designate the
+primary author and contact.
+
+Primary assignee:
+  <launchpad-id or None>
+
+Other contributors:
+  <launchpad-id or None>
+
+Work Items
+----------
+
+Work items or tasks -- break the feature up into the things that need to be
+done to implement it. Those parts might end up being done by different people,
+but we're mostly trying to understand the timeline for implementation.
+
+
+Dependencies
+============
+
+* Include specific references to specs and/or blueprints in vitrage, or in other
+  projects, that this one either depends on or is related to.
+
+* If this requires functionality of another project that is not currently used
+  by Vitrage, document that fact.
+
+* Does this feature require any new library dependencies or code otherwise not
+  included in OpenStack? Or does it depend on a specific version of library?
+
+
+Testing
+=======
+
+Please discuss how the change will be tested. We especially want to know what
+tempest tests will be added. It is assumed that unit test coverage will be
+added so that doesn't need to be mentioned explicitly, but discussion of why
+you think unit tests are sufficient and we don't need to add more tempest
+tests would need to be included.
+
+Is this untestable in gate given current limitations (specific hardware /
+software configurations available)? Is this untestable in vitrage-ci? If so,
+are there mitigation plans (3rd party testing, gate enhancements, etc).
+
+
+Documentation Impact
+====================
+
+What is the impact on the docs team of this change? Some changes might require
+donating resources to the docs team to have the documentation updated. Don't
+repeat details discussed above, but please reference them here.
+
+
+References
+==========
+
+Please add any useful references here. You are not required to have any
+reference. Moreover, this specification should still make sense when your
+references are unavailable. Examples of what you could include are:
+
+* Links to mailing list or IRC discussions
+
+* Links to notes from a summit session
+
+* Links to relevant research, if appropriate
+
+* Related specifications as appropriate (e.g.  if it's an EC2 thing, link the
+  EC2 docs)
+
+* Anything else you feel it is worthwhile to refer to
