-#### Flatpak-Kanäle (nightly / beta / stable)
-
-Das Flatpak-Repository enthält drei Kanäle, die alle im selben Remote liegen:
-
-| Kanal | Inhalt | Wird gebaut bei |
-|---|---|---|
-| `stable` | Aktuelle stabile Version | Jedem normalen Release-Tag |
-| `beta` | Vorab-Version | Tags mit `beta-` Präfix |
-| `nightly` | Entwicklungsstand (main-Branch) | Täglich / jedem Push auf main |
-
-Remote einmalig hinzufügen, dann den gewünschten Kanal installieren:
-
-```bash
-flatpak remote-add --if-not-exists kst4contest https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
-
-# Stable (Standard)
-flatpak install kst4contest de.x08.KST4Contest
-
-# Beta
-flatpak install kst4contest de.x08.KST4Contest//beta
-
-# Nightly
-flatpak install kst4contest de.x08.KST4Contest//nightly
-```
-
-> **Hinweis:** Flatpak erlaubt nur eine installierte Version pro App-ID gleichzeitig. Um den Kanal zu wechseln, zuerst die aktuelle Version deinstallieren:
-> ```bash
-> flatpak uninstall de.x08.KST4Contest
-> flatpak install kst4contest de.x08.KST4Contest//nightly
-> ```
-
-Updates erfolgen wie gewohnt mit `flatpak update`.
-
-Die `flatpakref`-Dateien für Beta und Stable liegen jeweils im entsprechenden [GitHub-Release](https://github.com/praktimarc/kst4contest/releases). Das Nightly-`flatpakref` (`de.x08.KST4Contest.nightly.flatpakref`) ist als Artifact im [GitHub Actions](https://github.com/praktimarc/kst4contest/actions)-Tab verfügbar (wird 14 Tage aufbewahrt) – der Remote-Weg oben ist für Nightly daher meist einfacher.

-#### Flatpak Channels (nightly / beta / stable)
-
-The Flatpak repository provides three channels, all served from the same remote:
-
-| Channel | Content | Built on |
-|---|---|---|
-| `stable` | Current stable version | Every normal release tag |
-| `beta` | Pre-release version | Tags prefixed with `beta-` |
-| `nightly` | Development build (main branch) | Every push to main / daily |
-
-Add the remote once, then install the channel you want:
-
-```bash
-flatpak remote-add --if-not-exists kst4contest https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
-
-# Stable (default)
-flatpak install kst4contest de.x08.KST4Contest
-
-# Beta
-flatpak install kst4contest de.x08.KST4Contest//beta
-
-# Nightly
-flatpak install kst4contest de.x08.KST4Contest//nightly
-```
-
-> **Note:** Flatpak only allows one installed version per App-ID at a time. To switch channels, uninstall the current version first:
-> ```bash
-> flatpak uninstall de.x08.KST4Contest
-> flatpak install kst4contest de.x08.KST4Contest//nightly
-> ```
-
-Updates work as usual with `flatpak update`.
-
-The `flatpakref` files for beta and stable are attached to their respective [GitHub Releases](https://github.com/praktimarc/kst4contest/releases). The nightly `flatpakref` (`de.x08.KST4Contest.nightly.flatpakref`) is available as an artifact on the [GitHub Actions](https://github.com/praktimarc/kst4contest/actions) tab (kept for 14 days) — for nightly builds, the manual remote approach above is usually more convenient.
