+The Policy Framework GUI Server
+###############################
+
+The **gui-server** microservice serves the GUI code to the browser for Policy Framework UI. In addition, it acts as
+a single point of reference for the REST interfaces provided by **policy-api**, **policy-pap**, and **acm-runtime**.
+It can also be used as a HTTPS gatewy for REST references into a Policy Framework deployment in a Kubernetes cluster.
+
+.. contents::
+    :depth: 2
+
+The **gui-server** is a regular microservice, and it is packaged, delivered and configured as a docker image. It is
+a Spring application and therefore uses a normal Spring-style *applciation.yaml* approach to configuration.
+
+Definitive example configurations are available in the codebase:
+
+- `application_http.yaml <https://github.com/onap/policy-gui/blob/master/gui-server/src/test/resources/application_http.yaml>`_
+  showing how to configure gui-server for HTTP access
+- `application_https.yaml <https://github.com/onap/policy-gui/blob/master/gui-server/src/test/resources/application_https.yaml>`_
+  showing how to configure gui-server for HTTPS access
+
+The configuration parameters are explained in the sections below
+
+Server Configuration
+--------------------
+
+Configuration for HTTP access to gui-server::
+
+  server:
+    port: 2443
+    ssl:
+      enabled: false
+
+Start gui-server on port 2443 and disable SSL.
+
+Configuration for HTTPS access to gui-server::
+
+  server:
+    port: 2443
+    ssl:
+      enabled: true
+      enabled-protocols: TLSv1.2
+      client-auth: want
+      key-store: file:./src/test/resources/helloworld-keystore.jks
+      key-store-password: changeit
+      trust-store: file:./src/test/resources/helloworld-truststore.jks
+      trust-store-password: changeit
+
+Start gui-server on port 2443 and enable SSL with the parameters specified above
+
+Note that other standard Spring **server** configuraiton parameters as
+documented
+`on the Spring website <https://docs.spring.io/spring-boot/docs/current/reference/html/application-properties.html>`_
+are supported.
+
+Runtime Adaptation Configuration
+--------------------------------
+
+You can configure the adaptation for **policy-api**, **policy-pap**, and **runtime-acm**. In other words, you can map
+the URL that the GUI produced or that you want to use in a REST tool such as *postman* or *curl* in the **runtime-ui**
+part of the aaplication.yaml file::
+
+  runtime-ui:
+    policy-api:
+      mapping-path: "/runtime-ui/policy-api/restservices/"
+      url: http://localhost:30440
+      disable-ssl-validation: true
+      disable-ssl-hostname-check: true
+    policy-pap:
+      mapping-path: "/runtime-ui/policy-pap/restservices/"
+      url: http://localhost:30442
+      disable-ssl-validation: true
+      disable-ssl-hostname-check: true
+    acm:
+      mapping-path: "/runtime-ui/acm/restservices/"
+      url: http://localhost:30258
+      disable-ssl-validation: true
+      disable-ssl-hostname-check: true
+
+The parameters under the **policy-api**, **policy-pap**, and **acm** sections are identical.
+
+mapping-path and url
+++++++++++++++++++++
+
+The **mapping-path** is the root part of the path that will be replaced by the **url**, the **url** replaces the
+**mapping-path**.
+
+Therefore, using the configuration above for policy-api, the following mapping occurs::
+
+  http://localhost:2443/runtime-ui/policy-api/restservices/policy/api/v1/healthcheck
+
+  maps to
+
+  http://localhost:30440/policy/api/v1/healthcheck
+
+and::
+
+  https://localhost:2443/runtime-ui/acm/restservices/onap/policy/clamp/acm/v2/commission
+
+  maps to
+
+  http://localhost:30258/onap/policy/clamp/acm/v2/commission
+
+disable-ssl-validation and disable-ssl-hostname-check
++++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+The **disable-ssl-validation** **disable-ssl-hostname-check** are boolean values. If the target server (policy-api,
+policy-pap, or runtime-acm) is using http, these values should be set to **false**. If the target server is using
+HTTPS, set the values as **true** so that the **gui-server** transfers and forwards certificates to target servers.
+
+Spring Boot Acuator Monitoring
+------------------------------
+
+The **gui-server** supports regular
+`Spring Boot Actuator monitoring <https://docs.spring.io/spring-boot/docs/1.4.0.M2/reference/html/production-ready-monitoring.html>`_
+and monitoring over `prometheus <https://prometheus.io/>`_.
+
+The following section of the *application.yaml** file is an example of how to enable monitoring::
+
+  management:
+    endpoints:
+      web:
+        base-path: /
+        exposure:
+          include: health,metrics,prometheus
+        path-mapping.metrics: plain-metrics
+        path-mapping.prometheus: metrics
+
+The configuration above enables the following URLs::
+
+  # Health Check
+  http://localhost:2443/health
+
+  # Plain Metrics
+  http://localhost:2443/plain-metrics
+
+  # Prometheus Metrics
+  http://localhost:2443/metrics
+
+

+The Policy Framework User Interfaces
+####################################
+
+The Policy Framework has a demonstration user interface that supports design time and runtime activities for the Policy
+Framework.
+
+Design time activities are offline activities such as policy editing and ACM composition preparation. The design time UI
+works with offline files, producing artifacts that can be consumed by the runtime Policy Framework APIs.
+
+Runtime operations include creating and updating policy types and policies, deploying policies as well as working with
+Automation Compositions. The runtime UI works towards the REST APIs published by the Policy Framework.
+
+.. image:: images/UIArchitecture.png
+
+.. note::
+   The policy framework UI is developed for use in demonstrations. It is a work in progress. As such, it does not cover
+   all the features and functions that are avaiable on the Policy Framework REST APIs.
+
+A Policy Framework installation in Kubernetes is shown in the figure above. The **policy-api**, **policy-pap** and
+**acm-runtime** microservices publish REST interfaces. In a Service Mesh installation, these interfaces are exposed
+over HTTP and are available inside the Service Mesh. Alternatively, the interfaces may be exposed publicly over HTTPS.
+
+The **gui-server** microservice serves the GUI code to the browser for Policy Framework UI. In addition, it acts as
+a single point of reference for the REST interfaces provided by **policy-api**, **policy-pap**, and **acm-runtime**.
+It can also be used as a HTTPS gatewy for REST references into a Policy Framework deployment in a Kubernetes cluster.
+
+The Policy Framework UI runs in a browser as a Web application. It has a **designtime** and a **runtime** part.
