+### PR-Kommando fuer PHP-CS-Fixer
+
+Bei Pull Requests kann per Kommentar ein Auto-Fix gestartet werden:
+
+```text
+/fix-cs
+```
+
+Was passiert dann:
+
+- GitHub Action fuehrt php-cs-fixer im Write-Mode auf dem PR-Branch aus.
+- Falls Aenderungen entstehen, werden sie automatisch committed und auf denselben Branch gepusht.
+- Anschliessend schreibt die Action einen Ergebnis-Kommentar in den PR.
+
+Hinweise:
+
+- Das Kommando ist auf Kommentare von `OWNER`, `MEMBER` und `COLLABORATOR` beschraenkt.
+- Fork-PRs werden aus Sicherheitsgruenden nicht automatisch gepusht.
