+# Contao Meilisearch Bundle
+
+Eine schlanke Schnittstelle zwischen **Contao CMS (4.13 / 5.6 / 5.7 ready) unter PHP 8.4** und einer **selbst gehosteten Meilisearch-Instanz**.  
+Das Bundle erweitert den Contao-Suchindex um strukturierte Daten und ermöglicht eine performante, moderne Volltextsuche.
+
+---
+
+## ✨ Features
+
+- Integration von **Meilisearch** als externe Suchmaschine
+- Indexierung von:
+    - Contao-Seiten
+    - Inhaltselementen
+    - **PDF-Dateien**
+    - **Office-Dokumenten** (DOCX, XLSX, PPTX)
+- Unterstützung für:
+    - Seiten-Prioritäten
+    - Keywords
+    - Vorschaubild
+- Kompatibel mit:
+    - Contao **4.13**, **5.6** und **5.7**
+    - PHP **8.4**
+
+---
+
+## ⏱️ Scheduled Indexing (Cron setup)
+
+Das Bundle stellt eigene Commands zur Verfügung, um Dateien zu bereinigen und den Meilisearch-Index neu aufzubauen.  
+Für den produktiven Einsatz wird empfohlen, diese Commands regelmäßig per **System-Crontab** auszuführen.
+
+Das Bundle nutzt **keinen eigenen Contao-Cron**, sondern System-Cronjobs.
+
+## Verfügbare Commands
+
+### Datei-Cleanup
+
+```
+/vendor/bin/contao-console meilisearch:files:cleanup
+```
+
+### Meilisearch-Index
+
+```
+/vendor/bin/contao-console meilisearch:index
+```
+
+## Empfohlene Reihenfolge
+
+1. Datei-Cleanup  
+   `/vendor/bin/contao-console meilisearch:files:cleanup`
+
+2. Contao-Crawl (ca. 1 Minute später)  
+   `/vendor/bin/contao-console contao:crawl`
+
+3. Meilisearch-Index (ca. 15 Minuten später)  
+   `/vendor/bin/contao-console meilisearch:index`
+
+## Beispiel Crontab
+
+```
+0 5 * * *  /usr/bin/php8.4 /path/to/project/vendor/bin/contao-console meilisearch:files:cleanup
+1 5 * * *  /usr/bin/php8.4 /path/to/project/vendor/bin/contao-console contao:crawl
+15 5 * * * /usr/bin/php8.4 /path/to/project/vendor/bin/contao-console meilisearch:index
+```
