 For detached mode, you also need to use the `-d` flag. You also need to supply a `conduit.toml` config file, you can find an example [here](../conduit-example.toml).
-You can pass in more env vars as are shown here, for an overview of possible values, you can take a look at the `docker-compose.yml` file.
+You can pass in different env vars to change config values on the fly. You can even configure Conduit completely by using env vars, but for that you need
+too pass `-e CONDUIT_CONFIG=""` into your container. For an overview of possible values, please take a look at the `docker-compose.yml` file.
 If you just want to test Conduit for a short time, you can use the `--rm` flag, which will clean up everything related to your container after you stop it.
