# Device definitions

### Core idea

{% hint style="info" %}
Each device has its own definitions directory.
{% endhint %}

They are all inside the DMT USER directory, under `~/.dmt/user/devices`.

{% hint style="success" %}
All device definitions are also replicated to all your devices.
{% endhint %}

### Device directory

Each device has a name and this is usually used as a subdirectory, like this:

```
mkdir ~/.dmt/user/devices/my_server
```

### Device definition directory

```
mkdir ~/.dmt/user/devices/[device_name]/def
```
