+# Gitea Act Runner (Oracle Cloud ARM64 / Docker)
+
+Docker Compose Setup für den Gitea CI/CD Runner zum automatischen Bauen der Android-APKs.
+
+## Schnellstart
+
+1. **Token holen:**
+   In Gitea unter **Website-Verwaltung** (oder Repo-Einstellungen) ➔ **Aktionen** ➔ **Runner** ➔ **Neuen Runner erstellen** das Registrierungs-Token kopieren.
+
+2. **Konfiguration erstellen:**
+   ```bash
+   cp .env.example .env
+   nano .env
+   ```
+   Dort das kopierte Token bei `GITEA_RUNNER_REGISTRATION_TOKEN` eintragen.
+
+3. **Runner starten:**
+   ```bash
+   docker compose up -d
+   ```
+
+4. **Logs ansehen:**
+   ```bash
+   docker compose logs -f
+   ```
