+Automatically upgrade firmware and reboot
+=========================================
+
+[◀ Go back to main README](../README.md)
+
+🛈 This script can not be used on its own but requires the base installation.
+See [main README](../README.md) for details.
+
+Description
+-----------
+
+RouterOS and firmware are upgraded separately, activating the latter
+requires an extra reboot. This script handles upgrade and reboot.
+
+⚠️ **Warning**: This *should* be bullet proof, but I can not guarantee. In
+worst case it has potential to cause a boot loop, so handle with care!
+
+Requirements and installation
+-----------------------------
+
+Just install the script and create a scheduler:
+
+    $ScriptInstallUpdate firmware-upgrade-reboot;
+    / system scheduler add name=firmware-upgrade-reboot on-event="/ system script run firmware-upgrade-reboot;" start-time=startup;
+
+Enjoy firmware being up to date and in sync with RouterOS.
