+# Cazubu - Pflanzenverwaltung
+
+Cazubu ist eine Webanwendung zur Verwaltung von Pflanzen, Inventar, Samen und Sensoren.
+
+## Funktionen
+- Pflanzenübersicht und Details
+- Inventarverwaltung
+- Samen-Datenbank
+- Sensor-Integration
+- Benutzerverwaltung (Login/Register)
+
+## Installation & Betrieb
+
+### Voraussetzungen
+- Docker
+- Externe MySQL-Datenbank
+
+### Docker Build & Run
+
+Das Projekt ist für den Betrieb im Docker-Container vorbereitet.
+
+1. **Image bauen:**
+   ```bash
+   docker build -t cazubu .
+   ```
+
+2. **Container starten:**
+   Es müssen die Datenbank-Verbindungsdaten als Umgebungsvariablen übergeben werden.
+   
+   ```bash
+   docker run -d -p 8080:80 \
+     -e DB_SERVER="deine-db-ip" \
+     -e DB_USERNAME="dein-db-user" \
+     -e DB_PASSWORD="dein-db-passwort" \
+     -e DB_NAME="cazubu" \
+     --name cazubu-app \
+     cazubu
+   ```
+
+### Umgebungsvariablen
+
+| Variable | Beschreibung | Standard |
+|----------|--------------|----------|
+| `DB_SERVER` | IP oder Hostname des Datenbankservers | `172.30.242.130` |
+| `DB_USERNAME` | Datenbank-Benutzer | `cazubu` |
+| `DB_PASSWORD` | Datenbank-Passwort | (interner Standard) |
+| `DB_NAME` | Name der Datenbank | `cazubu` |
+
+## Changelog
+
+### 2025-12-07 - Dockerisierung
+- `Dockerfile` erstellt (PHP 8.2 + Apache + MySQLi/GD).
+- `.dockerignore` hinzugefügt.
+- CI/CD Pipeline Konfiguration `.gitea/workflows/build-push.yaml` hinzugefügt.
+- `includes/db_connect.php` angepasst: Unterstützung für Umgebungsvariablen hinzugefügt.
+- `README.md` erstellt.
