+Important notes
+===============
+
+OPNFV Doctor project started as a requirement project and identified gaps
+between "as-is" open source software (OSS) and an "ideal" platform for NFV.
+Based on this analysis, the Doctor project proposed missing features to
+upstream OSS projects. After those features were implemented, OPNFV installer
+projects integrated the features to the OPNFV platform and the OPNFV
+infra/testing projects verified the functionalities in the OPNFV Labs.
+
+This document provides an overview of the Doctor project in the OPNFV Colorado
+release, including new features, known issues and documentation updates.
+
+New features
+============
+
+* **Congress as a Doctor Inspector**
+
+  Since `Doctor driver`_ in OpenStack Congress has been implemented in Mitaka,
+  OpenStack Congress can now take the role of the Doctor Inspector to correlate
+  an error in a physical resource to the affected virtual resource(s)
+  immediately.
+
+.. _Doctor driver: https://review.openstack.org/#/c/314915/
+
+Installer support and verification status
+=========================================
+
+Integrated features
+-------------------
+
+Minimal Doctor functionality of VIM is available in the OPNFV platform from
+the Brahmaputra release. The basic Doctor framework in VIM consists of a
+Controller (Nova) and a Notifier (Ceilometer+Aodh) along with a sample
+Inspector and Monitor developed by the Doctor team.
+From the Colorado release, key integrated features are:
+
+* Immediate notification upon state update of virtual resource enabled by
+  Ceilometer and Aodh (Aodh integration)
+
+* Consistent state awareness improved by having nova API to mark nova-compute
+  service down (Nova: Force compute down)
+
+* Consistent state awareness improved by exposing host status in server (VM)
+  information via Nova API (Nova: Get valid service status)
+
+* OpenStack Congress enabling policy-based flexible failure correlation
+  (Congress integration)
+
+OPNFV installer support matrix
+------------------------------
+
+In the Brahmaputra release, only one installer (Apex) supported the deployment
+of the basic doctor framework by configuring Doctor features. In the Colorado
+release, integration of Doctor features progressed in other OPNFV installers.

+
+Documentation updates
+=====================
+
+* **Alarm comparison**
+
+  A report on the gap analysis across alarm specifications in ETSI NFV IFA,
+  OPNFV Doctor and OpenStack Aodh has been added, along with some proposals
+  on how to improve the alignment between SDO specification and OSS
+  implementation as a future work (`DOCTOR-46`_).
+
+.. _DOCTOR-46: https://jira.opnfv.org/browse/DOCTOR-46
+
+* **Description of test scenario**
+
+  The description of the Doctor scenario, which is running as one of the
+  feature verification scenarios in Functest, has been updated (`DOCTOR-53`_).
+
+.. _DOCTOR-53: https://jira.opnfv.org/browse/DOCTOR-53
+
+* **Neutron port status update**
+
+  Design documentation for port status update has been added, intending to
+  propose new features to OpenStack Neutron.
+
+* **SB I/F specification**
+
+  The initial specification of the Doctor southbound interface, which is for
+  the Inspector to receive event messages from Monitors, has been added
+  (`DOCTOR-17`_).
+
+.. _DOCTOR-17: https://jira.opnfv.org/browse/DOCTOR-17
+
+Known issues
+============
+
+* **Aodh 'event-alarm' is not available as default (Fuel)**
+
+  In Fuel 9.0, Aodh integration for 'event-alarm' is not completed.
+  Ceilometer and Nova would be mis-configured and cannot pass event
+  notification to Aodh.
+  You can use `fuel-plugin-doctor`_ to correct Ceilometer and Nova
+  configuration as a workaround. See `DOCTOR-62`_.
+
+.. _fuel-plugin-doctor: https://github.com/openzero-zte/fuel-plugin-doctor
+.. _DOCTOR-62: https://jira.opnfv.org/browse/DOCTOR-62
+
+* **Security notice**
+
+  Security notice has been raised in [*]_. Please insure that the debug option
+  of Flask is set to False, before running in production.
+
+.. [*] http://lists.opnfv.org/pipermail/opnfv-tech-discuss/2016-September/012610.html
+
+* **Performance issue in correct resource status (Fuel)**
+
+  Although the Doctor project is aiming to ensure that the time interval
+  between detection and notification to the user is less than 1 second, we
+  observed that it takes more than 2 seconds in the default OPNFV deployment
+  using the Fuel installer [*]_.
+  This issue will be solved by checking the OpenStack configuration and
+  improving Doctor testing scenario.
