# Internationalization

> Multi-language interface support

BotMux supports English and Russian in the web interface.

## Usage

Toggle the language using the **EN/RU** button in the sidebar header. The preference is saved in `localStorage` and applied instantly without page reload.

## Implementation

Translations are defined in the `i18n` object in `templates/index.html` with keys for `en` and `ru`. The `t(key)` function returns the string for the current language. `applyLang()` re-renders all static and dynamic content.
