+## For systemd users
+
+- `libvips` is no longer required (unless your server os is *BSD), so you may uninstall it from your system. Make sure to execute the following commands after that:
+    ```sh
+    pnpm clean-npm
+    pnpm install
+    ```
+
 ## For Docker/Podman users
 
 - The image tag has been changed to `registry.firefish.dev/firefish/firefish:latest`, so please update `docker-compose.yml`.
