# How to add machines
Clan has two general methods of adding machines
- **Automatic**: Detects every folder in the `machines` folder.
- **Declarative**: Explicit declarations in nix.
## Automatic register
Every machine of the form `machines/{machineName}` will be registered automatically.
Automatically imported:
- [x] ``machines/{machineName}/configuration.nix`
- [x] ``machines/{machineName}/hardware-configuration.nix`
- [x] ``machines/{machineName}/facter.json` Automatically configured, for further information see [nixos-facter](../blog/posts/nixos-facter.md)
## Manual declaration
Machines can also be added manually under `buildClan`, `clan.*` in flake-parts or via [`inventory`](../guides/inventory.md).
!!! Note
It is possible to use `inventory` and `buildClan` together at the same time.
=== "**Individual Machine Configuration**"
```{.nix}
buildClan {
machines = {
"jon" = {
# Any valid nixos config
};
};
}
```
=== "**Inventory Configuration**"

buildClan {
inventory = {
machines = {
"jon" = {
# Inventory machines can set tags
tags = [ "zone1" ];

This guide will walk you through setting up a backup service, where the inventory becomes useful.
## Prerequisites Meta (optional)
!!! example "Experimental status"
The inventory implementation is not considered stable yet.
We are actively soliciting feedback from users.
Metadata about the clan, will be displayed upfront in the upcomming clan-app, make sure to choose a unique name.
Stabilizing the API is a priority.
Make sure to set `name` either via `inventory.meta` OR via `clan.meta`.

## How to add machines
## Prerequisites
Every machine of the form `machines/{machineName}/configuration.nix` will be registered automatically.
Machines can also be manually added under `inventory.machines` OR via `buildClan` directly.
!!! Note
It doesn't matter where the machine gets introduced to buildClan - All delarations are valid, duplications are merged.
However the clan-app (UI) will create machines in the inventory, because it cannot create arbitrary nix code or nixos configs.
In the following example `backup_server` is one machine - it may specify parts of its configuration in different places.
```{.nix hl_lines="3-5 12-20"}
buildClan {
machines = {
"backup_server" = {
# Any valid nixos config
};
"jon" = {
# Any valid nixos config
};
};
inventory = {
machines = {
"backup_server" = {
# Don't include any nixos config here.
# See the Inventory API Docs for the available attributes.
};
"jon" = {
# Same as above
};
};
};
}
```

## Services
### Available clanModules
The inventory defines `services`. Membership of `machines` is defined via roles exclusively.
Currently the inventory interface is implemented by the following clanModules
- [borgbackup](../reference/clanModules/borgbackup.md)
- [packages](../reference/clanModules/packages.md)
- [single-disk](../reference/clanModules/single-disk.md)
See the respective module documentation for available roles.
