+| Variable | Type | Default | Description |
+|----------|------|---------|-------------|
+| `NOTES_DIR` | string | `./data` | Path to the notes vault |
+| `PLUGINS_DIR` | string | `./plugins` | Path to the plugins directory |

+INFO:     Notes directory: /home/me/MyVault (from NOTES_DIR env var)
+INFO:     Plugins directory: ./plugins (from config.yaml)
