+Dependencies

+This project uses various frameworks which are managed with Maven
+dependency management tool (see *pom.xml* file at root level) :
+
+- Swagger annotations
+- `Spring Framework <https://github.com/spring-projects/spring-boot>`_
+- `Springfox <https://github.com/springfox/springfox>`_ Automated JSON API documentation for API's built with Spring
+- `Immutable <https://immutables.github.io/>`_ to generate simple, safe and consistent value objects
+- `JSON in Java <https://github.com/stleary/JSON-java>`_ to parse JSON documents into Java objects
+- `Apache Commons Net <https://github.com/apache/commons-net>`_ for network utilities and protocol implementations
+- `DCAE SDK <https://github.com/onap/dcaegen2-services-sdk>`_ to get configuration from CBS
+- `Lombok <https://github.com/rzwitserloot/lombok>`_ to generate code, such as getters and setters
+- `Awaitility <https://github.com/awaitility/awaitility>`_ to test asynchronous functionality
+
+Configuration
+-------------
+
+There are two configuration files for PMS, *config/application_configuration.json* and *config/application.yaml*.
+The first one contains configuration of data needed by the application, such as which Near-RT RICs
+that are available. The second contains logging and security configurations.
+
 Configuration of certs

 The Policy Management Service uses the default keystore and truststore that are built into the container. The paths and passwords for these stores are located in a yaml file:

+================

+The NON-RT RIC Control Panel in O-RAN-SC can be used to interact with the Policy Management Service.
+See `NON-RT RIC Control Panel repo <https://gerrit.o-ran-sc.org/r/admin/repos/portal/nonrtric-controlpanel>`_.
+
+Any "Rest Client" application may be used (Postman, ...) to interact with the Policy Management Service application.
