 **Field** | **Type** | **Required**| **Description**
 --- | --- | --- | ---
+**`language`** | `string` | _Optional_ | The 2 (or 4-digit) [ISO 639-1 code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) for your language, e.g. `en` or `en-GB`. This must be a language that the app has already been [translated](https://github.com/Lissy93/dashy/tree/master/src/assets/locales) into. If your language is unavailable, Dashy will fallback to English. By default Dashy will attempt to auto-detect your language, although this may not work on some privacy browsers.
 **`statusCheck`** | `boolean` | _Optional_ | When set to `true`, Dashy will ping each of your services and display their status as a dot next to each item. This can be overridden by setting `statusCheck` under each item. Defaults to `false`
 **`statusCheckInterval`** | `boolean` | _Optional_ | The number of seconds between checks. If set to `0` then service will only be checked on initial page load, which is usually the desired functionality. If value is less than `10` you may experience a hit in performance. Defaults to `0`
 **`backgroundImg`** | `string` | _Optional_ | Path to an optional full-screen app background image. This can be either remote (http) or local (/). Note that this will slow down initial load
