+## Docker
+
+### Building the image
+
+With Docker installed, simply enter
+```bash
+docker build -t dhconvalidator .
+```
+
+### Running a container
+
+To run the 'dhconvalidator' image you created in the step above enter 
+```bash
+docker run -d --rm -p8080:8080 --name dhconvalidator dhconvalidator 
+```
+This will spin up a container with the default settings, making 
+the DHConvalidator instance available at `http://localhost:8080/dhconv`.
+
+#### Parameters (and default values) available to the Docker container

+
+You can overwrite the default settings via environment variables, e.g. 
+```bash
+docker run -d --rm -p8080:8080 --name dhconvalidator -e dhconvalidator_base_url=http://my.dhconvalidator.base.url dhconvalidator 
+```
+will set the base url to `http://my.dhconvalidator.base.url`. 
+
+### Docker-compose with OxGarage sidekick
+
+`docker-compose` allows you to easily run your own dedicated OxGarage 
+instance as a sidekick to the DHConvalidator.
