# colmena anywhere
A thin wrapper around [nixos-anywhere](https://github.com/numtide/nixos-anywhere)
to build with colmena
Colmena configurations must use disko.
Have a look to schedar machine config in [../config/machines/schedar](../config/machines/schedar)
# usage
```
$ ./colmena-anywhere.sh --help
```
Colmena nixpkgs version must provide nixos-anywhere (eg: with an overlay)
