# Multi-Language Support

Charon speaks your language. The interface is available in English, Spanish, French, German, and Chinese. Switch languages instantly in settings—no reload required.

## Overview

Charon's interface is fully localized, making it accessible to users worldwide. All UI elements, error messages, and documentation links adapt to your selected language. Language switching happens instantly in the browser without requiring a page reload or server restart.

## Supported Languages

| Language | Code | Status |
|----------|------|--------|
| English | `en` | Complete (default) |
| Spanish | `es` | Complete |
| French | `fr` | Complete |
| German | `de` | Complete |
| Chinese (Simplified) | `zh` | Complete |

## Why Use This

- **Native Experience**: Use Charon in your preferred language
- **Team Accessibility**: Support multilingual teams
- **Instant Switching**: Change languages without interruption
- **Complete Coverage**: All UI elements are translated

## Changing Language

To change the interface language:

1. Click your **username** in the top-right corner
2. Select **Settings**
3. Find the **Language** dropdown

The interface updates immediately—no reload required.

### Per-User Setting

Language preference is stored per user account. Each team member can use Charon in their preferred language independently.

## Browser Language Detection

On first visit, Charon attempts to detect your browser's language preference. If a supported language matches, it's selected automatically. You can override this in settings at any time.
