+Notify on RouterOS update
+=========================
+
+[◀ Go back to main README](../README.md)
+
+Description
+-----------
+
+The primary use of this script is to notify about RouterOS updates.
+
+Run from a terminal you can start the update process or schedule it.
+
+Centrally managing update process of several devices is possibly by
+specifying versions safe to be updated on a web server.
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate check-routeros-update;
+
+And add a scheduler for automatic update notification:
+
+    / system scheduler add interval=1d name=check-routeros-update on-event="/ system script run check-routeros-update;" start-time=startup;
+
+Configuration
+-------------
+
+Configuration is required only if you want to control update process with
+safe versions from a web server. The configuration goes to
+`global-config-overlay`, this is the parameter:
+
+* `SafeUpdateUrl`: url to check for safe update, the channel (`long-term`,
+`stable` or `testing`) is appended
+
+Usage and invocation
+--------------------
+
+Be notified when run from scheduler or run it manually:
+
+    / system script run check-routeros-update;
+
+If an update is found you can install it right away.
+
+Installing script [packages-update](packages-update.md) gives extra options.
