-You may additionally want to run end-to-end tests using the jouled
-process. The configuration directory contains an main.conf file and
-corresponding stream and module configurations to run a local joule
-instance. To automate this testing you can run the joule process in
-Docker. See the e2e testing section in Joule for an example.
+This repository also contains an end-to-end test suite in the e2e
+directory. This suite uses docker-compose to build a NilmDB and Joule
+container for testing. See docker documentation for details on installing
+docker compose: https://docs.docker.com/compose/
