+
+The PMSH is configured and deployed via CLAMP.
+
+Application specific configuration
+""""""""""""""""""""""""""""""""""
+
+The application config is the basic information that PMSH needs to run. The following parameters are required, they are
+specified in the CLAMP deployment GUI.

+
+::
+
+        AAI-EVENT
+
+This topic is used so that the PMSH can listen for new NFs getting registered. If the NF matches the NF filter (See

+
+::
+
+        org.onap.dmaap.mr.PM_SUBSCRIPTION_EVENTS
+
+This topic is used for locking and unlocking events. i.e if a user has previously created a locked

+
+Publisher:
+^^^^^^^^^^
+
+::
+
+        org.onap.dmaap.mr.PM_SUBSCRIPTIONS
+
+The PMSH publishes subscriptions to this topic. They will be consumed by a policy which will make a request to CDS to
+unlock the subscription.

+Introduction
+""""""""""""
+The PM Subscription Handler (PMSH) is a micro service written in Python, which allows for the definition and unlocking
+of PM subscriptions on one or more network function (NF) instances.
+
+.. _Delivery: ./delivery.html
+
+Functionality
+"""""""""""""
+The PMSH allows for the definition of subscriptions on a network level, which enables the
+configuration of PM data on a set of NF instances.
+
+Interaction
+"""""""""""
+
+Config Binding Service
+^^^^^^^^^^^^^^^^^^^^^^
+
+The PMSH interacts with the Config Binding Service to retrieve it's configuration information, including the
+subscription information.
+
+DMaaP
+^^^^^
+
+The PMSH subscribes and publishes to various DMaaP Message Router topics (See :ref:`Topics<Topics>`
+for more information on which topics are used).
+
+A&AI
+^^^^
+
+The PMSH interacts with A&AI to fetch data about network functions. The ``nfFilter`` is then
+applied to this data to produce a targeted subset of NF's.
+
+Policy and CDS
+^^^^^^^^^^^^^^
+
+The PMSH will indirectly interact with Policy and CDS in order to push subscriptions to NF's. A policy will be used to
+make a request to CDS, which will apply the subscription to the NF.
+
+
+
+

+Troubleshooting
+===============
+
+Configuration Errors
+""""""""""""""""""""
+
+If the PMSH fails to start and is in CrashLoopBackOff, it is likely due to a configuration error.
+
+Unable to connect to Config Binding Service
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The PMSH may not be able to reach the Config Binding Service. If this is the case you will be able to
+see an error connecting to Config Binding Service in Kibana.
+
+Invalid Configuration
+^^^^^^^^^^^^^^^^^^^^^
+
+If the PMSH is able to connect to Config Binding Service, but is failing to start. It may be due to
+invalid configuration. Check Kibana for an incorrect configuration error.
