 Repo lokal ziehen und den Addon-Pfad in den Preferences auf den Repo-Ordner
 zeigen lassen.
 
+## Installation als Extension (via URL, mit Auto-Update)
+
+Ab Blender 4.2 / 5.x als **Remote-Extension-Repository** – einmal die URL
+eintragen, danach gehen Updates per Klick.
+
+1. Das Gitea-Repo muss **oeffentlich** sein (sonst kann Blender die Raw-URL nicht
+   ohne Login laden).
+2. Blender → *Edit → Preferences → Get Extensions → oben rechts das Dropdown →
+   Repositories → „Add Remote Repository"*.
+3. Als URL eintragen:
+
+   ```
+   https://git.d4rkst3r.de/D4rkst3r/stylized-rock-generator/raw/branch/main/dist/index.json
+   ```
+
+4. „Check for Updates" aktivieren, bestaetigen. Die Extension erscheint in der
+   Liste → *Install*.
+
+**Updaten (Maintainer-Seite):**
+
+1. `version` in `blender_manifest.toml` (und `bl_info["version"]` in der `.py`) erhoehen.
+2. `./build.ps1` (oder `blender --command extension build …` + `… server-generate …`).
+3. `git add -A && git commit -m "vX.Y.Z" && git push`.
+4. Nutzer: in Blender *Check for Updates* → *Update*.
+
+Das gebaute Zip + `index.json` liegen in `dist/` und werden bewusst mitversioniert,
+damit die Raw-URL sie ausliefert.
