### 3. Update Configuration File

Edit `src/main/resources/fess_config.properties`:

Find the `supported.languages` property (around line 202) and ensure your language code is included:

```properties

    protected void writeFessConfig(final ZipOutputStream zos, final String id) {
        if (fessConfig instanceof SimpleImpl) {
            final Properties prop = new Properties();
            ((SimpleImpl) fessConfig).keySet().stream().forEach(k -> prop.setProperty(k, fessConfig.get(k)));

            final ZipEntry entry = new ZipEntry(id + "/fess_config.properties");
            try {
                zos.putNextEntry(entry);
