+MR Topics
+"""""""""""""""""""""
+
+Subscriber:
+^^^^^^^^^^^
+
+::
+
+ 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
+:ref:`Configuration<Configuration>`) it will be added to the relevant subscription. This topic is **AAI_EVENT**.
+
+::
+
+ 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
+subscription, they can publish an event to this topic to unlock it, or vice versa.
+
+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. \ No newline at end of file

+Installation
+============
+
+The PMSH will be configured and instantiated through CLAMP. During instantiation, the PMSH will fetch its configuration

+
+Deployment Prerequisites
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+In order to succesfully deploy the PMSH, the following components are required to be running. They
+can be verified by running the healtchecks.
+
+ - DCAE Platform
+ - DMaaP
+ - SDC
+ - CLAMP
+ - A&AI
+ - AAF

+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.
+
+
+

+
+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. \ No newline at end of file
