+====================================
+Enabling OPNFV Doctor using DevStack
+====================================
+
+This directory contains the files necessary to run OpenStack with enabled
+OPNFV Doctor in DevStack.
+
+To configure DevStack to enable OPNFV Doctor edit
+``${DEVSTACK_DIR}/local.conf`` file and add::
+
+    enable_plugin aodh http://git.openstack.org/openstack/aodh
+    enable_plugin panko https://git.openstack.org/openstack/panko
+    enable_plugin ceilometer https://git.openstack.org/openstack/ceilometer
+    enable_plugin osprofiler https://git.openstack.org/openstack/osprofiler
+    enable_plugin doctor https://git.opnfv.org/doctor
+
+to the ``[[local|localrc]]`` section.
+
+.. note:: The order of enabling plugins matters.
+
+Run DevStack as normal::
+
+    $ ./stack.sh
