+=============================
+ The title of your blueprint
+=============================
+
+Include the URL of your launchpad blueprint:
+
+https://blueprints.launchpad.net/zaqar/+spec/example
+
+Introduction paragraph -- why are we doing anything?
+
+Driver description
+==================
+
+A detailed description of the driver.
+
+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?
+
+What are the driver's guarantees in terms of reliability?
+=========================================================
+
+"Zaqar aims to be a fully-reliable service, therefore messages should  never be
+lost under any circumstances except for when the message's  expiration time
+(ttl) is reached..."
+
+What are the driver's guarantees in terms of scalability?
+=========================================================
+
+Zaqar aims to be an easily scalable service. Zaqar provides an easy way to
+scale web-heads and to balance queue's load across several different storage
+clusters. However, the real scalability is provided by the storage itself. If
+the storage can't be unlimitedly scaled or it's hard to scale, it'll break this
+guarantee. Supported storage must be good for general use-cases and easy to
+scale unlimitedly. It's fine to have storage drivers for very specific
+use-cases but it's likely not going to be possible to maintain those drivers.
+
+What are the driver's guarantees in terms of interoperability?
+==============================================================
+
+In order for applications to easily talk to different clouds supporting Zaqar,
+it is necessary for the service to guarantee interoperability as much as
+possible. Lots of the interoperability guarantees depend on how the service
+itself is deployed. However, the team strives to provide an interoperable
+service and guide operators on what the best way to deploy the service is.
+
+What are the driver's guarantees in terms of openness?
+======================================================
+
+Zaqar is an open-source software licensed under the Apache 2 license. It aims
+to be able to be installed in any deployments and circumstances. In order to do
+that, it tries to support technologies that will alow deployers to do so
+without any constraint. In order for the team to be able to maintain and
+support a storage driver, the driver has to be licensed under an open license
+and so has to be the technology the driver supports. The team won't be able to
+maintain drivers relying on closed technologies that cannot be tested/deployed.
+
+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>
+
+Can list additional ids if they intend on doing substantial implementation work
+on this blueprint.
+
+Milestones
+----------
+
+Target Milestone for completion:
+  Juno-2
+
+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
