# Changed
- Instead of environment variables, we use now a .env file.
- Added new variables for more modular environment:
  ```
  MINIO_SERVER="terminology-server.dcc.sib.swiss"
  MINIO_PORT="9000"
  TS_USER="<terminology-server-username>"
  TS_PASSWORD="<terminology-server-password>"
  HTTPS_PROXY="<optional-proxy-server>"
  ```
