# Reference Manual: disko
## Module Options
We are currently having issues being able to generate proper module option
documentation for our recursive disko types. However you can read the available
options [here](https://github.com/nix-community/disko/tree/master/lib/types).
Combined with the
[examples](https://github.com/nix-community/disko/tree/master/example) this
hopefully gives you an overview.
## Command Line Options
```
Usage: ./disko [options] disk-config.nix
or ./disko [options] --flake github:somebody/somewhere#disk-config
With flakes, disk-config is discovered first under the .diskoConfigurations top level attribute
or else from the disko module of a NixOS configuration of that name under .nixosConfigurations.
Options:
* -m, --mode mode
set the mode, either distroy, format, mount, format,mount or destroy,format,mount
destroy: unmount filesystems and destroy partition tables of the selected disks
format: create partition tables, zpools, lvms, raids and filesystems if they don't exist yet
mount: mount the partitions at the specified root-mountpoint
format,mount: run format and mount in sequence
destroy,format,mount: run all three modes in sequence. Previously known as --mode disko
* -f, --flake uri
fetch the disko config relative to this flake's root
* --arg name value
pass value to nix-build. can be used to set disk-names for example
* --argstr name value
pass value to nix-build as string
* --root-mountpoint /some/other/mnt
where to mount the device tree (default: /mnt)
* --dry-run
just show the path to the script instead of running it
* --no-deps
avoid adding another dependency closure to an in-memory installer
requires all necessary dependencies to be available in the environment
* --debug
run with set -x
* --yes-wipe-all-disks
skip the safety check for destroying partitions, useful for automation
