+Task Scheduler
+##############
+
+The task scheduler allows you to execute tasks on a given schedule. It makes
+use of UNIX cron_.
+
+.. note:: All scripts excecuted this way are executed as root user - this may
+   be dangerous. Together with :ref:`command-scripting` this can be used for
+   automating (re-)configuration.
+
+.. cfgcmd:: set system task-scheduler task <task> interval <interval>
+
+   Specify the time interval when `<task>` should be executed. The interval
+   is specified as number with one of the following suffixes:
+
+   * ``none`` - Execution interval in minutes
+   * ``m`` - Execution interval in minutes
+   * ``h`` - Execution interval in hours
+   * ``d`` - Execution interval in days
+
+   .. note:: If suffix is omitted, minutes are implied.
+
+.. cfgcmd:: set system task-scheduler task <task> crontab-spec <spec>
+
+   Set execution time in common cron_ time format. A cron `<spec>` of
+   ``30 */6 * * *`` would execute the `<task>` at minute 30 past every 6th hour.
+
+.. cfgcmd:: set system task-scheduler task <task> executable path <path>
+
+   Specify absolute `<path>` to script which will be run when `<task>` is
+   executed.
+
+.. cfgcmd:: set system task-scheduler task <task> executable arguments <args>
+
+   Arguments which will be passed to the executable.
