+========================
+Cron - Inactivity Period
+========================
+
+
+This module allows you to disable cron Jobs during periods.
+It can be usefull if you want to disable your cron jobs during maintenance
+period, or for other reasons.
+
+Note
+----
+
+If you have installed ``cron_run_manually`` module, it is still possible to run
+your job, during inactivity periods.
+
+Configuration
+=============
+
+To configure this module, you need to:
+
+#. Go to Settings > Technical > Automation > Scheduled Actions and select a
+   cron
+#. Add new option inactivity periods

+   :align: center
+
+
+Known issues / Roadmap
+======================
+
+* For the time being, only one type of inactivity period is available. ('hour')
+  It should be great to add other options like 'week_day', to allow user to
+  disable cron jobs for given week days.
