+Rotting lead detection
+----------------------
+
+.. note::
+   The *Days to rot* feature is only available to apps that use stages, for instance,
+   **CRM** and **Heldesk** apps. This feature is automatically disabled by setting it to zero.
+
+The *Days to rot* feature provides proactive notification when a specific card within
+that stage requires attention. When a card passes the defined rotting threshold, it becomes
+highlighted in red and the stage displays the total number of cards currently rotting.

+:icon:`oi-view-kanban` :guilabel:`(Kanban)` icon.
+
+To set the threshold for a stage, click on the :icon:`fa-gear` :guilabel:`(Settings)` icon for the
+relevant stage and select :guilabel:`Edit` from the drop-down menu. A configuration window will
+appear.
+
+In the :guilabel:`Days to rot` field, enter the number of days that marks the threshold before
+action is needed. Click :guilabel:`Save` to apply the configuration.
