 ##### Docker Secrets
 
-All environment variables set can be overwritten by appending `_FILE` to the variable value.For example, you can use `PASSWORD_FILE` to pass through a docker secret instead of `PASSWORD`. If both `PASSWORD` and `PASSWORD_FILE` are set, the docker secret will take precedent. An example using docker secrets is available in [here](.docker/docker-compose.yml).
