### How do I install a custom image?
In order to download an unsupported ISO image, specify its URL in the `VERSION` environment variable:
```yaml
environment:
VERSION:"https://example.com/win.iso"
```
Alternatively, you can also skip the download and use a local file instead, by binding it in your compose file in this way:
```yaml
volumes:
-./example.iso:/custom.iso
```
Replace the example path `./example.iso` with the filename of your desired ISO file. The value of `VERSION` will be ignored in this case.
### How do I run a script after installation?
To run your own script after installation, you can create a file called `install.bat` and place it in a folder together with any additional files it needs (software to be installed for example).
Then bind that folder in your compose file like this:
```yaml
volumes:
-./example:/oem
```
The example folder `./example` will be copied to `C:\OEM` and the containing `install.bat` will be executed during the last step of the automatic installation.
### How do I perform a manual installation?
It's best to stick to the automatic installation, as it adjusts various settings to prevent common issues when running Windows inside a virtual environment.
However, if you insist on performing the installation manually, add the following environment variable to your compose file:
```yaml
environment:
MANUAL:"Y"
```
