| For Docker/Podman users:                                 |
| docker-compose.yml has now been renamed to               |
| docker-compose.example.yml. So you need to restore it by |
| $ cp docker-compose.example.yml docker-compose.yml       |
|                                                          |
| For the detailed explanation, see:                       |
