+
+Thanks for trying out Umbrel!
+
+This install script is for advanced users who already have an existing system they want to install Umbrel on. We recommend running Umbrel OS on a Raspberry Pi for the best experience.
+
+Umbrel is currently in beta and is not yet safe to be exposed to the internet, it should only be run on a secure private network.
+
+This installation method assumes a fresh Debian install. If you already have Docker or Docker Compose installed you may wish to exclude them with --no-install-docker or --no-install-compose.
+
+You can pass flags to the installer like this:
+
+  curl https://umbrel.sh | bash -s -- --no-install-docker --no-install-compose
+
+You may press Ctrl+C now to abort the install.
+
