+#### Test requirements
+Tests require a postgres database for tests to run. The easiest way to accomplish this is with docker. This project offers
+a docker-compose file at tests/conf/dev.docker-compose.yaml. You can use this file with
+
+```console
+$ docker compose -f tests/conf/dev.docker-compose.yaml up -d
+```
+
+After testing you can tear down the running containers with
+
+```console
+$ docker compose -f tests/conf/dev.docker-compose.yaml down
+```
