 Occasionally, squads that you send out on a mission get stuck on the world map.
 They lose their ability to navigate and are unable to return to your fortress.
-This tool finds another of your squads that is returning from a mission and
-assigns them to rescue the lost squad.
+This tool allows another of your squads that is (successfully) returning from a
+mission to rescue the lost squad along the way and bring them home.
 
 This fix is enabled by default in the DFHack
 `control panel <gui/control-panel>`, or you can run it as needed. However, it
 is still up to you to send out another squad that can be tasked with the rescue
-mission. You can send the rescue squad out on an innocuous "Demand tribute"
-mission to minimize risk to the squad.

+
+This tool is integrated with `gui/notify`, so you will get a notification in
+the DFHack notification panel when a squad is stuck and there are no squads
+currently out traveling that can rescue them.
+
+Note that there might be other reasons why your squad appears missing -- if it
+got wiped out in combat and nobody survived to report back, for example -- but
+this tool should fix the cases that are actual bugs.
