+## Installation aus der Gitea-Paket-Registry
+
+Über die CI/CD-Pipelines werden bei jedem Push auf den `main`-Branch (Release / Stable) und `dev`-Branch (Preview /
+Testing) automatisch Pakete für **Debian/Ubuntu**, **Fedora/RHEL** und **Arch Linux** in der Gitea-Paket-Registry
+bereitgestellt.
+
+### 1. Debian / Ubuntu (`apt`)
+
+#### Stable (Produktiv)
+
+Füge das Repository zu deinen APT-Quellen hinzu:
+
+```bash
+# Keyring installieren
+sudo curl https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/debian/repository.key -o /etc/apt/keyrings/gitea-Linuxapps.asc
+# Repository-Eintrag anlegen
+echo "deb [signed-by=/etc/apt/keyrings/gitea-Linuxapps.asc] https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/debian stable main" | sudo tee -a /etc/apt/sources.list.d/gitea.list
+
+# Paketliste aktualisieren und installieren
+sudo apt update
+sudo apt install docker-update
+```
+
+#### Testing (Vorschau / Dev)
+
+```bash
+# Keyring installieren
+sudo curl https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/debian/repository.key -o /etc/apt/keyrings/gitea-Linuxapps.asc
+# Testing-Repository-Eintrag anlegen
+echo "deb [signed-by=/etc/apt/keyrings/gitea-Linuxapps.asc] https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/debian testing main" | sudo tee -a /etc/apt/sources.list.d/gitea.list
+
+# Paketliste aktualisieren und installieren
+sudo apt update
+sudo apt install docker-update
+```
+
+---
+
+### 2. Fedora / RHEL / CentOS (`dnf` / `yum`)
+
+#### Stable (Produktiv)
+
+Erstelle die Repository-Datei `/etc/yum.repos.d/docker-update.repo`:
+
+```bash
+sudo tee /etc/yum.repos.d/docker-update-stable.repo << 'EOF'
+[docker-update-stable]
+name=DockerUpdate Stable
+baseurl=https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/rpm/stable
+enabled=1
+gpgcheck=0
+EOF
+
+# Installation via DNF
+sudo dnf install docker-update
+```
+
+#### Testing (Vorschau / Dev)
+
+```bash
+sudo tee /etc/yum.repos.d/docker-update-testing.repo << 'EOF'
+[docker-update-testing]
+name=DockerUpdate Testing
+baseurl=https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/rpm/testing
+enabled=1
+gpgcheck=0
+EOF
+
+# Installation via DNF
+sudo dnf install docker-update
+```
+
+---
+
+### 3. Arch Linux (`pacman`)
+
+#### Stable (Produktiv)
+
+Füge das Repository in `/etc/pacman.conf` ein:
+
+```ini
+[docker-update-stable]
+SigLevel = Optional TrustAll
+Server = https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/arch/stable/$arch
+```
+
+Installiere das Paket anschließend:
+
+```bash
+sudo pacman -Sy docker-update
+```
+
+#### Testing (Vorschau / Dev)
+
+Füge das Testing-Repository in `/etc/pacman.conf` ein:
+
+```ini
+[docker-update-testing]
+SigLevel = Optional TrustAll
+Server = https://gitea.creative-dragonslayer.de/api/packages/Linuxapps/arch/testing/$arch
+```
+
+Installiere das Paket:
+
+```bash
+sudo pacman -Sy docker-update
+```
+
+---
+
+### Download vorgefertigter Pakete (Releases)
+
+Alternativ können vorkompilierte Pakete (`.deb`, `.rpm`, `.pkg.tar.zst`) auch direkt aus den Releases heruntergeladen
+und manuell installiert werden:
+
+- **Stable-Releases**: [Gitea Releases](https://gitea.creative-dragonslayer.de/Linuxapps/DockerUpdate/releases)
+- **Preview-Releases (Testing)**: Markiert als Vorabveröffentlichung (*Pre-release*) mit dem Tag `v<VERSION>-preview`.
