 Upgrading your existing install without changing your configuration is very straightforward. To upgrade to the [latest release](https://github.com/billz/raspap-webgui/releases/latest) version, simply run the [Quick Installer](https://github.com/billz/raspap-webgui/wiki/Quick-Installer-usage) with the `--upgrade` option:
 
 ```
-curl -sL https://install.raspap.com | bash -s --upgrade
+curl -sL https://install.raspap.com | bash -s -- --upgrade
 ```
 
 The installer upgrade is _idempotent_, meaning it can be repeated an arbitrary number of times and the result will be as if it had been done only once. For example, previously installed packages will be skipped if their state is unchanged.
