# Configuration
## Introduction
When managing machine configuration this can be done through many possible ways.
Ranging from writing `nix` expression in a `flake.nix` file; placing `autoincluded` files into your machine directory; or configuring everything in a simple UI (upcomming).
clan currently offers the following methods to configure machines:
!!! Success "Recommended for nix people"
- flake.nix (i.e. via `buildClan`)
- `machine` argument
- `inventory` argument
- machines/`machine_name`/configuration.nix (`autoincluded` if it exists)
???+ Note "Used by CLI & UI"
- inventory.json
- machines/`machine_name`/hardware-configuration.nix (`autoincluded` if it exists)
!!! Warning "Deprecated"
machines/`machine_name`/settings.json
## BuildClan
The core function that produces a clan. It returns a set of consistent configurations for all machines with ready-to-use secrets, backups and other services.
### Inputs
`directory`
: The directory containing the machines subdirectory
`machines`
: Allows to include machine-specific modules i.e. machines.${name} = { ... }
`meta`
: An optional set
: `{ name :: string, icon :: string, description :: string }`
`inventory`
: Service set for easily configuring distributed services, such as backups
: For more details see [Inventory](./inventory.md)
`specialArgs`
: Extra arguments to pass to nixosSystem i.e. useful to make self available
`pkgsForSystem`
: A function that maps from architecture to pkgs, if specified this nixpkgs will be only imported once for each system.
This improves performance, but all nipxkgs.* options will be ignored.
`(string -> pkgs )`
