+### convertToUtf8 (Japanese text file -> UTF-8)
+
+`DaitoString::convertToUtf8()` converts Japanese-encoded text files to UTF-8.
+
+- Prefer `nkf` when available
+- Fallback to `mb_convert_encoding` when `nkf` is unavailable
+
+Install `nkf` (Ubuntu/Debian):
+
+```bash
+sudo apt install nkf
+```
+
+Example:
+
+```php
+DaitoString::convertToUtf8('/tmp/source.csv');
+DaitoString::convertToUtf8('/tmp/source.csv', '/tmp/out', 'source_utf8.csv', 1);
+```

 ## QueryLog (Laravel shared package)
 
+> **Provider registration note**
+> 
+> This package supports Laravel package auto-discovery via `composer.json`:

+> 
+> In normal cases, child projects do **not** need to register the provider manually.
+> If a child project uses `"dont-discover"` for this package, add it manually in
+> `config/app.php`:

+> 'providers' => [
+>   // ...
