+# Internationalisierung (i18n) Dokumentation
+
+Hördle unterstützt vollständige Mehrsprachigkeit (Internationalisierung) für Deutsch und Englisch.
+
+## Übersicht
+
+Die i18n-Implementierung basiert auf [next-intl](https://next-intl-docs.vercel.app/) und nutzt den Next.js App Router mit dynamischen `[locale]`-Segmenten.
+
+## Unterstützte Sprachen
+
+- **Deutsch (de)** - Standardsprache
+- **Englisch (en)**
+
+## URL-Struktur
+
+Alle Routen sind lokalisiert:
+
+- `http://localhost:3000/` → Redirect zu `/de` (Standard)
+- `http://localhost:3000/de` → Deutsche Version
+- `http://localhost:3000/en` → Englische Version
+- `http://localhost:3000/de/admin` → Admin-Dashboard (Deutsch)
+- `http://localhost:3000/de/Rock` → Rock Genre (Deutsch)
+- `http://localhost:3000/de/special/Weihnachtslieder` → Special (Deutsch)
+

+  navigation.ts          # Lokalisierte Navigation (Link, useRouter, etc.)
+```
+
+### Übersetzungsdateien
+
+Die Übersetzungen sind in JSON-Dateien unter `messages/` organisiert:
+
+```json
+{
+  "Common": {
+    "loading": "Laden...",
+    "error": "Ein Fehler ist aufgetreten"
+  },
+  "Game": {
+    "play": "Abspielen",
+    "pause": "Pause",
+    "won": "Gewonnen!"
+  },
+  "Home": {
+    "welcome": "Willkommen bei Hördle"
+  }
+}
+```
+
+### Datenbank-Schema
+
+Die folgenden Modelle unterstützen mehrsprachige Felder:
+
+#### Genre
+- `name`: JSON `{ "de": "Rock", "en": "Rock" }`
+- `subtitle`: JSON `{ "de": "Klassischer Rock", "en": "Classic Rock" }`
+
+#### Special
+- `name`: JSON `{ "de": "Weihnachtslieder", "en": "Christmas Songs" }`
+- `subtitle`: JSON `{ "de": "Festliche Musik", "en": "Festive Music" }`
+
+#### News
+- `title`: JSON `{ "de": "Neues Feature", "en": "New Feature" }`
+- `content`: JSON `{ "de": "Markdown Inhalt...", "en": "Markdown content..." }`
+
+### Helper-Funktionen
+
+#### `getLocalizedValue(value, locale, fallback?)`
+
+Extrahiert den lokalisierten Wert aus einem JSON-Objekt:
+
+```typescript
+import { getLocalizedValue } from '@/lib/i18n';
+
+const genreName = getLocalizedValue(genre.name, 'de'); // "Rock"
+const genreNameEn = getLocalizedValue(genre.name, 'en'); // "Rock"
+```
+
+**Fallback-Verhalten:**
+1. Versucht die angeforderte Locale (`de` oder `en`)
+2. Fallback zu `de` falls nicht vorhanden
+3. Fallback zu `en` falls nicht vorhanden
+4. Fallback zum ersten verfügbaren Schlüssel
+5. Fallback zum übergebenen `fallback`-Parameter
+
+#### `createLocalizedObject(de, en?)`
+
+Erstellt ein lokalisiertes Objekt:
+
+```typescript
+import { createLocalizedObject } from '@/lib/i18n';
+
+const name = createLocalizedObject('Rock', 'Rock');
+// { de: "Rock", en: "Rock" }
+```
+
+## Verwendung in Komponenten
+
+### Server Components
+
+```typescript
+import { getTranslations } from 'next-intl/server';
+import { getLocalizedValue } from '@/lib/i18n';
+
+export default async function Page({ params }: { params: { locale: string } }) {
+  const { locale } = await params;
+  const t = await getTranslations('Home');
+  
+  const genreName = getLocalizedValue(genre.name, locale);
+  
+  return <h1>{t('welcome')}</h1>;
+}
+```
+
+### Client Components
+
+```typescript
+'use client';
+import { useTranslations } from 'next-intl';
+import { useLocale } from 'next-intl';
+
+export default function Game() {
+  const t = useTranslations('Game');
+  const locale = useLocale();
+  
+  return <button>{t('play')}</button>;
+}
+```
+
+### Navigation
+
+Verwende die lokalisierte Navigation aus `lib/navigation.ts`:
+
+```typescript
+import { Link } from '@/lib/navigation';
+
+// Automatisch lokalisiert
+<Link href="/admin">Admin</Link>
+<Link href="/Rock">Rock</Link>
+```
+
+## Admin-Interface
+
+Das Admin-Dashboard unterstützt mehrsprachige Eingaben:
+
+1. **Sprach-Tabs:** Wechsle zwischen `DE` und `EN` Tabs
+2. **Genre/Special/News:** Alle Felder können in beiden Sprachen bearbeitet werden
+3. **Vorschau:** Sieh dir die lokalisierte Version direkt an
+
+### Beispiel: Genre erstellen
+
+1. Öffne `/de/admin`
+2. Wähle den `DE` Tab
+3. Gib Name und Subtitle ein
+4. Wechsle zum `EN` Tab
+5. Gib die englischen Übersetzungen ein
+6. Speichere
+
+## Migration bestehender Daten
+
+Bestehende Daten werden automatisch migriert:
+
+1. **Migration `20251128131405_add_i18n_columns`:** Fügt neue JSON-Spalten hinzu
+2. **Migration `20251128132806_switch_to_json_columns`:** Konvertiert String-Spalten zu JSON
+
+**Wichtig:** Alte String-Werte werden automatisch in beide Sprachen kopiert:
+- `"Rock"` → `{ "de": "Rock", "en": "Rock" }`
+
+## Middleware
+
+Die Middleware (`middleware.ts`) leitet Anfragen automatisch um:
+
+- `/` → `/de` (Standard)
+- Ungültige Locales → 404
+- Validiert Locale-Parameter
+
+## Sprachumschalter
+
+Die `LanguageSwitcher`-Komponente ermöglicht Nutzern, zwischen Sprachen zu wechseln:
+
+```typescript
+import LanguageSwitcher from '@/components/LanguageSwitcher';
+
+<LanguageSwitcher />
+```
+
+Die aktuelle Route bleibt erhalten, nur die Locale ändert sich:
+- `/de/admin` → `/en/admin`
+- `/de/Rock` → `/en/Rock`
+
+## API-Endpunkte
+
+API-Routen unterstützen einen optionalen `locale`-Parameter:
+
+```typescript
+GET /api/genres?locale=de
+GET /api/specials?locale=en
+GET /api/news?locale=de
+```
+
+Falls kein `locale` angegeben wird, wird `de` als Standard verwendet.
+
+## Best Practices
+
+### 1. Immer `getLocalizedValue` verwenden
+
+❌ **Falsch:**
+```typescript
+<span>{genre.name}</span> // Rendert { de: "...", en: "..." }
+```
+
+✅ **Richtig:**
+```typescript
+<span>{getLocalizedValue(genre.name, locale)}</span>
+```
+
+### 2. Übersetzungsschlüssel konsistent benennen
+
+Verwende Namespaces für bessere Organisation:
+- `Common.*` - Allgemeine UI-Elemente
+- `Game.*` - Spiel-spezifische Texte
+- `Home.*` - Homepage-Texte
+- `Navigation.*` - Navigations-Elemente
+
+### 3. Fallbacks definieren
+
+Immer einen Fallback-Wert angeben:
+
+```typescript
+const name = getLocalizedValue(genre.name, locale, 'Unbekannt');
+```
+
+### 4. Neue Übersetzungen hinzufügen
+
+1. Füge den Schlüssel zu `messages/de.json` hinzu
+2. Füge den Schlüssel zu `messages/en.json` hinzu
+3. Verwende `useTranslations('Namespace')` oder `getTranslations('Namespace')`
+
+## Troubleshooting
+
+### 404-Fehler auf `/de` oder `/en`
+
+**Problem:** Route wird nicht gefunden.
+
+**Lösung:**
+1. Überprüfe, ob `middleware.ts` korrekt konfiguriert ist
+2. Stelle sicher, dass `app/[locale]/layout.tsx` existiert
+3. Prüfe die `i18n/request.ts` Konfiguration
+
+### "Objects are not valid as a React child"
+
+**Problem:** Ein JSON-Objekt wird direkt gerendert statt des lokalisierten Werts.
+
+**Lösung:**
+Verwende `getLocalizedValue()`:
+
+```typescript
+// ❌ Falsch
+<span>{genre.name}</span>
+
+// ✅ Richtig
+<span>{getLocalizedValue(genre.name, locale)}</span>
+```
+
+### Übersetzungen werden nicht angezeigt
+
+**Problem:** Texte erscheinen als Schlüssel (z.B. `"Game.play"`).
+
+**Lösung:**
+1. Überprüfe, ob der Übersetzungsschlüssel in `messages/de.json` und `messages/en.json` existiert
+2. Stelle sicher, dass der Namespace korrekt ist: `useTranslations('Game')` für `Game.play`
+3. Prüfe die JSON-Syntax auf Fehler
+
+### Admin-Interface zeigt Objekte statt Text
+
+**Problem:** In Dropdowns oder Listen werden `{ de: "...", en: "..." }` angezeigt.
+
+**Lösung:**
+Verwende `getLocalizedValue()` in allen Render-Funktionen:
+
+```typescript
+// ❌ Falsch
+<option value={s.id}>{s.name}</option>
+
+// ✅ Richtig
+<option value={s.id}>{getLocalizedValue(s.name, activeTab)}</option>
+```
+
+## Erweiterung um weitere Sprachen
+
+Um eine neue Sprache hinzuzufügen (z.B. Französisch):
+
+1. **Übersetzungsdatei erstellen:**
+   ```bash
+   cp messages/de.json messages/fr.json
+   ```
+
+2. **Übersetzungen hinzufügen:**
+   Bearbeite `messages/fr.json` mit französischen Übersetzungen
+
+3. **Locale zur Konfiguration hinzufügen:**
+   - `i18n/request.ts`: `const locales = ['en', 'de', 'fr'];`
+   - `middleware.ts`: `locales: ['en', 'de', 'fr']`
+   - `lib/navigation.ts`: `export const locales = ['de', 'en', 'fr'] as const;`
+
+4. **Layout aktualisieren:**
+   ```typescript
+   // app/[locale]/layout.tsx
+   if (!['en', 'de', 'fr'].includes(locale)) {
+     notFound();
+   }
+   ```
+
+5. **LanguageSwitcher erweitern:**
+   Füge einen Button für `fr` hinzu
+
+6. **Datenbank-Migration:**
+   Bestehende Daten behalten ihre Struktur, neue Einträge können optional `fr` enthalten

+# White Labeling Guide
+
+This application is designed to be easily white-labeled. You can customize the branding, colors, and configuration without modifying the core code.
+
+## Configuration
+
+The application is configured via environment variables. You can set these in a `.env` or `.env.local` file.
+
+### Branding
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `NEXT_PUBLIC_APP_NAME` | The name of the application. | `Hördle` |
+| `NEXT_PUBLIC_APP_DESCRIPTION` | The description used in metadata. | `Daily music guessing game...` |
+| `NEXT_PUBLIC_DOMAIN` | The domain name (used for sharing). | `hoerdle.elpatron.me` |
+| `NEXT_PUBLIC_TWITTER_HANDLE` | Twitter handle for metadata. | `@elpatron` |
+
+### Analytics (Plausible)
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `NEXT_PUBLIC_PLAUSIBLE_DOMAIN` | The domain to track in Plausible. | `hoerdle.elpatron.me` |
+| `NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC` | The URL of the Plausible script. | `https://plausible.elpatron.me/js/script.js` |
+
+### Credits
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `NEXT_PUBLIC_CREDITS_ENABLED` | Enable/disable footer credits (`true`/`false`). | `true` |
+| `NEXT_PUBLIC_CREDITS_TEXT` | Text before the link. | `Vibe coded with ☕ and 🍺 by` |
+| `NEXT_PUBLIC_CREDITS_LINK_TEXT` | Text of the link. | `@elpatron@digitalcourage.social` |
+| `NEXT_PUBLIC_CREDITS_LINK_URL` | URL of the link. | `https://digitalcourage.social/@elpatron` |
+
+## Theming
+
+The application uses CSS variables for theming. You can override these variables in your own CSS file or by modifying `app/globals.css`.
+
+### Key Colors
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `--primary` | Main action color (buttons). | `#000000` |
+| `--secondary` | Secondary actions. | `#4b5563` |
+| `--accent` | Accent color. | `#667eea` |
+| `--success` | Success state (correct guess). | `#22c55e` |
+| `--danger` | Error state (wrong guess). | `#ef4444` |
+| `--warning` | Warning state (stars). | `#ffc107` |
+| `--muted` | Muted backgrounds. | `#f3f4f6` |
+
+### Example: Red Theme
+
+To create a red-themed version, add this to your CSS:
+
+```css
+:root {
+  --primary: #dc2626;
+  --accent: #ef4444;
+  --accent-gradient: linear-gradient(135deg, #ef4444 0%, #b91c1c 100%);
+}
+```
+
+## Assets
+
+To replace the logo and icons:
+1.  Replace `public/favicon.ico`.
+2.  Replace `public/icon.png` (if it exists).
+3.  Update `app/manifest.ts` if you have custom icon paths.
+3.  Update `app/manifest.ts` if you have custom icon paths.
+
+## Docker Deployment
+
+When deploying with Docker, please note that **Next.js inlines `NEXT_PUBLIC_` environment variables at build time**.
+
+This means you cannot simply change the environment variables in `docker-compose.yml` and restart the container to change the branding. You must **rebuild the image**.
+
+### Using Docker Compose
+
+1.  Create a `.env` file with your custom configuration:
+    ```bash
+    NEXT_PUBLIC_APP_NAME="My Music Game"
+    NEXT_PUBLIC_THEME_COLOR="#ff0000"
+    # ... other variables
+    ```
+
+2.  Ensure your `docker-compose.yml` passes these variables as build arguments (already configured in `docker-compose.example.yml`):
+    ```yaml
+    services:
+      hoerdle:
+        build:
+          context: .
+          args:
+            NEXT_PUBLIC_APP_NAME: ${NEXT_PUBLIC_APP_NAME}
+            # ...
+    ```
+
+3.  Build and start the container:
+    ```bash
+    docker compose up --build -d
+    ```
