+NF Simulator
+============
+
+Description
+-----------
+An idea behind NF (Network Function) Simulator is to introduce simulator, which supports ORAN defined O1 interface (reporting of NF events to Service Management Orchestrators).
+Within the use-case, it is expected, that an NF configuration change, happening due to multiple reasons (network mechanism triggered change - e.g. discovery of neighbours) is reported to the network management system, using ONAP`s VES REST events.
+The simulator is expected to cover planned NF behaviour - receive the config change via a NetConf protocol and report that change (also potentially other related changes) to the network management system using ONAP`s VES event.

+
+**Figure 1. Architecture Overview**
+
+NF Simulator code is stored in https://github.com/onap/integration-simulators-nf-simulator and all it's sub repos are:
+
+* for VES Client - https://github.com/onap/integration-simulators-nf-simulator-ves-client
+* for Netconf Server - https://github.com/onap/integration-simulators-nf-simulator-netconf-server
+* for AVCN Manager - https://github.com/onap/integration-simulators-nf-simulator-avcn-manager
+* for PM HTTPS Server - https://github.com/onap/integration-simulators-nf-simulator-pm-https-server
+
+For above components have been prepared:
+
+* docker images in ONAP Nexus:
+
+    *  VES Client image - nexus3.onap.org:10001/onap/org.onap.integration.nfsimulator.vesclient
+    *  AVCN Manager image - nexus3.onap.org:10001/onap/org.onap.integration.nfsimulator.avcnmanager
+    *  PM HTTPS Server image - nexus3.onap.org:10001/onap/org.onap.integration.nfsimulator.pmhttpsserver
+    *  Netconf Server images - nexus3.onap.org:10001/onap/org.onap.integration.nfsimulator.netconfserver
+
+* example helm charts:
+
+    * `Helm charts <https://github.com/onap/integration-simulators-nf-simulator/tree/master/helm>`_
+
+**VES Client, Netconf Server and PM HTTPS Server can be used and deployed separately depending on needs.**
+
+Only AVCN Manger connects VES Client with Netconf Server in order to support O1 interface.
+
+1. VES Client:
+--------------
+
+   Application that generates VES events on demand.
+
+   **What does it do?**
+
+   * Supports both basic auth and TLS CMPv2 method of authentication.
+   * Allows to turn on and turn off hostname, verification in SSL.
+   * Allows to send one-time event and periodic events, based on event templates.
+   * Exposes API to manage VES Client
+   * Provides template mechanism (Template is a draft event. Merging event with patch will result in valid VES event.
+     Template itself should be a correct VES event as well as valid json object. )
+   * Patching - User is able to provide patch in request, which will be merged into template.
+   * Simulator supports corresponding keywords in templates: RandomInteger(start,end), RandomPrimitiveInteger(start,end), RandomInteger,
+     RandomString(length), RandomString, Timestamp, TimestampPrimitive, Increment
+   * In place variables support - Simulator supports dynamic keywords e.g. #dN to automatically substitute selected phrases in defined json schema.
+   * Logging - Every start of simulator will generate new logs that can be found in docker ves-client container.
+   * Swagger - Detailed view of simulator REST API is available via Swagger UI
+   * History - User is able to view events history.
+
+
+2. Netconf Server:
+------------------
+
+   This server uses sysrepo to simulate network configuration.
+   It is based on sysrepo-netopeer2 image.
+
+   **What does it do?**
+
+   Server allows to:
+
+   * install custom configuration models on start up.
+   * change configuration of that modules on runtime.
+   * use TLS custom certificates
+   * configure change subscription for particular YANG modules (Netconf server image run python application on the startup.)
+   * manage netconf server using REST interface, with endpoints:
+
+      * GET /healthcheck returns 200 "UP" if server is up and running
+      * POST /readiness return 200 "Ready" if server is ready, if not, returns 503 "Not Ready"
+      * POST /change_config/<path:module_name> changes configuration ad returns 202 "Accepted"
+      * GET /change_history returns 200 and change history as json
+      * GET /get_config/<path:module_name> returns 200 and current configuration
+
+3. AVCN Manager:
+----------------
+
+   Manager that fetches changes of configuration from kafka and sends them to VES client.
+
+   **What does it do?**
+
+   The manager processes notifications from NETCONF server. It does this by being a subscriber of a Kafka topic that is fed
+   with NETCONF notifications. Incoming notifications are then processed and output of this processing is sent to VES client.
+
+4. PM HTTPS Server:
+-------------------
+
+   Server that is used in Bulk PM usecases over HTTPS
+
+   **What does it do?**
+
+   * Supports TLS (CMPv2) method of authentication (used during connection to Data File Collector)
+   * Allows to use custom certificates
+   * Exposes REST API in order to manage PM files stored in HTTPS server
