Hello.
If you have docker installed and configured, you can simply use kas-
container:
```
./kas/kas-container menu
```
- Distro Selection => Raspberry Pi OS Debian 12 (bookworm)
- Machine selection => rpi-arm-v7l # E.g. kernel for Raspberry 3B+
- Packages selection => Isar packages => You might want on;y `expand-
on-first-boot` from the list
- Packages selection => Distro packages => Add any packages from
RaspioOS mirrors
- User management => Activate 'root' user
Adjust other settings if you need. Exit menu and run build:
```
./kas/kas-container build
```
After the build finished you can use the image for SD-card:
`build/tmp/deploy/images/rpi-arm-v7l/isar-image-base-raspios-bookworm-
rpi-arm-v7l.wic`
