# Language codes

We use the ISO 639-1 codes for language settings. Examples are `Site.language_code` and the language codes used in text translation tables. We generally support the language code plus the regional dialect.

**Examples:**

* English - `en`
* English (United Kingdom) - `en-gb`

## Reference of ISO codes

Use the 639-1 column as reference.
