+## Usage
+To use one of the volume images, mount it as a volume to your existing SonarQube container using e.g. `docker-compose`:
+```
+version: "2"
+
+services:
+  sonarqube:
+    image: sonarqube:6.7.3-alpine # lts
+    ports:
+      - "80:9000"
+    networks:
+      - sonarnet
+    volumes:
+      - sonarqube_bundled-plugins:/opt/sonarqube/lib/bundled-plugins
+    volumes_from:
+      - plugins
+
+  plugins:
+    image: mwizner/sonarqube-scala-plugins:2.3.0
+    volumes:
+      - sonarqube_plugins:/opt/sonarqube/extensions/plugins
+    command: /bin/true
+
+  ...
+```
+
+You can get the full recipe from [here](https://github.com/mwz/sonar-scala-docker/blob/master/docker-compose.yml).
+
+To use the `full` image, run the following `docker` command:
+```bash
+docker run -d --name sonarqube-scala-plugins-full \
+  -p 80:9000 \
+  -e SONARQUBE_JDBC_USERNAME=sonar \
+  -e SONARQUBE_JDBC_PASSWORD=sonar \
+  -e SONARQUBE_JDBC_URL=jdbc:postgresql://localhost/sonar \
+  mwizner/sonarqube-scala-plugins:2.3.0-full
+```
+Please note that if you don't specify the `SONARQUBE_JDBC_URL` variable, SonarQube will use an embedded H2 database, which is not recommended in production.
