This guide explains how to add internationalization (i18n) support for a new language in Fess.

## Overview

Fess uses a two-tier language support system:

1. **Full UI Translation** (13 languages): Complete user interface translation with label and message files
2. **Search/Analysis Support** (40+ languages): Language-specific text analysis for search indexing
