# Translation

> Configure your provider key and translate your source strings.

## Setup Provider

anylang uses the provider configured in your `anylang.config.json` file. By default, it uses OpenRouter or Gemini.

Add your provider key to your `.env` file at the root of your project:

```env theme={null}
# For Gemini
GEMINI_API_KEY=your-provider-key

# For OpenRouter
OPENROUTER_API_KEY=your-provider-key
```

<Info>
  anylang is bring-your-own-key. Check out the [Providers](/providers) page for a full list of supported models (OpenAI, Anthropic, Mistral, etc.) and their corresponding environment variables.

## Translate

Once your key is configured, run the translation command:

```bash theme={null}
npx anylang translate
```

<Info>
  `translate` automatically scans your files first, retranslates any changed strings, and intelligently skips unchanged target entries to save on API costs.
</Info>

You're all set! Your `locales` folder will now be populated with the translated strings, and they will appear in your app.
