+- If you use custom invoice or voucher template, you will need to mount them in the docker by adding
+```yaml
+    volumes:
+      - /path/to/invoice/template:templates/default_invoive.html:ro
+      - /path/to/voucher/template:templates/default_voucher.html:ro
+```

+```yaml
+    volumes:
+      - /path/to/external/app:app:ro
+```
+- run `docker compose up`
