CPU_CORES: "4"
```
Please be aware that macOS may have issues when the configured CPU core count is not a power of two (2, 4, 8, 16, etc).
* ### How do I add multiple disks?
To create additional disks, modify your compose file like this:
```yaml
environment:
DISK2_SIZE: "32G"
DISK3_SIZE: "64G"
volumes:
- /home/example:/storage2
- /mnt/data/example:/storage3
```
* ### How do I pass-through a disk?
It is possible to pass-through disk devices directly by adding them to your compose file in this way:
```yaml
devices:
- /dev/sdb:/disk1
- /dev/sdc:/disk2
```
Use `/disk1` if you want it to become your main drive, and use `/disk2` and higher to add them as secondary drives.
* ### How do I pass-through a USB device?
To pass-through a USB device, first lookup its vendor and product id via the `lsusb` command, then add them to your compose file like this:
