+### Cleanup
+When you are done using the services, you can clean everything by running `down`.

+For example, in the scenario of the [Sample CouchDB data]({{< relref "#sample-couchdb-data" >}}), the command should look like:
+
+```sh
+docker compose -f docker-compose.couchdb.yml -f docker-compose.postgres.yml -f docker-compose.yml down

+To remove all the data volumes, add `-v` at the end of this command.
