+# Building and running dmi-plugin locally
+
+## Building Java Archive only
+
+Following command builds Java component to `ncmp-dmi-plugin/target/ncmp-dmi-plugin-x.y.z-SNAPSHOT.jar` JAR file
+without generating any docker images:
+
+```bash
+mvn clean install -Djib.skip
+```
+
+## Building Java Archive and Docker image
+
+* Following command builds the JAR file and also generates the Docker image for the dmi plugin:
+
+```bash
+mvn clean install
+```
+
+## Running Docker containers
+
+`docker-compose/docker-compose.yml` file is provided to be run with `docker-compose` tool and images previously built.
+It starts ncmp-dmi-plugin service.
+
+Execute following command from `docker-compose` folder:
+
+Use one of the below types that has been generated in the local system's docker image list after the build.
+```bash
+docker-compose up -d
+or
+VERSION=<version> docker-compose up -d
+or
+DOCKER_REPO=<docker.repo> docker-compose up -d
+or
+VERSION=<version> DOCKER_REPO=<docker_repo> docker-compose up -d
+```
+
+## Running or debugging Java built code
+
+dmi-plugin can be started either using a Java Archive previously built or directly from Intellij IDE.
+
+### Running from Jar Archive
+
+Following command starts the application using JAR file:
+
+```bash
+CPS_USERNAME=cpsuser CPS_PASSWORD=cpsr0cks! \
+  java -jar ncmp-dmi-plugin/target/ncmp-dmi-plugin-x.y.z-SNAPSHOT.jar
+```
+
+### Running from IntelliJ IDE
+
+Here are the steps to run or debug the application from Intellij:
+
+1. Enable the desired maven profile from Maven Tool Window
+2. Run a configuration from `Run -> Edit configurations` with following settings:
+   * `Environment variables`: `CPS_USERNAME=cpsuser CPS_PASSWORD=cpsr0cks!`
+
+## Accessing services
+
+Swagger UI and Open API specifications are available to discover service endpoints and send requests.
+
+* `http://localhost:<port-number>/swagger-ui/index.html`
+* `http://localhost:<port-number>/v3/api-docs?group=dmi-plugin-docket`
+
+with <port-number> being either `8080` if running the plain Java build or retrieved using following command
+if running from `docker-compose`:
+
+```bash
+docker inspect \
+  --format='{{range $p, $conf := .NetworkSettings.Ports}} {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' \
+  <dmi-plugin-docker-container>
+```
