With this method, it is even possible to switch between different versions while keeping all your file data intact.
If you don't have internet access, it's also possible to skip the download by setting URL to:
```yaml
environment:
URL:"DSM_VirtualDSM_42218.pat"
```
after placing a file called `DSM_VirtualDSM_42218.pat` in your `/storage` folder.
* ### What are the differences compared to the standard DSM?
There are only two minor differences: the Virtual Machine Manager package is not available, and Surveillance Station will not include any free licenses.
