-    :summary: Add dynamic configuration options for track stops.
+    :summary: Overlay to allow changing track stop and related building settings after construction.
     :tags: fort buildings interface
 
-This script provides 2 overlays that are managed by the `overlay` framework. The script does nothing when executed.
-The trackstop overlay allows the player to change the friction and dump direction of a selected track stop after it has been constructed.
-The rollers overlay allows the player to change the roller direction and speed of a selected roller after it has been constructed.
+This script provides 3 overlays that are managed by the `overlay` framework.
+The script does nothing when executed.
+
+The ``trackstop`` overlay allows the player to change the friction and dump
+direction of a selected track stop after it has been constructed.
+
+The ``rollers`` overlay allows the player to change the roller direction and
+speed of a selected roller after it has been constructed.
+
+The ``pressureplate`` overlay allows the player to change the trigger settings
+of a selected pressure plate after it has been constructed. Manual value entry
+of ranges for minecart and creature triggers is provided, allowing greater
+precision than the game interface normally permits. Incrementing or decrementing
+values always restricts them to the usual intervals.
