# Languages

**Where:** Project → Settings → Languages · `/projects/<project>/settings?tab=Languages`

Set the languages the project works with. Modules that render user-facing content — email, push and SMS templates — use them for localized variants.

## Fields

| Field               | What it does                                                                                                                                                                      |
| ------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Default Language    | A dropdown. The default is used for all new content items and for the project's public API when no language is given.                                                             |
| Supported languages | A badge list. **Edit** opens the language picker to add a language; removing a badge removes the language. Both changes save immediately and show **"Project settings updated"**. |

The default language is also available in templates as the `@Model.Project.DefaultLanguage` binding — see [Bindings](/cloud/project/settings/bindings.md).
