+.. dfhack-tool::
+    :summary: Resize armor and clothing.
+    :tags: adventure fort armok gameplay items
+
+Resize any armor or clothing item to suit any creature size.
+
+Usage
+-----
+
+``resize-armor [<option>]``
+
+Select an armor or clothing item while in either adventure or fortress mode and
+run this tool to resize the item. A stockpile can be selected while in fortress
+mode to perform the resize operation on armor or clothing items contained in
+the stockpile. If race ID is not specified, the items will be resized to suit
+the race of the current adventurer while in adventure mode, or to suit the race
+of the current site's civilization while in fortress mode.
+
+Options
+-------
+
+``-r``, ``--race <id>``
+    Specify the race ID of the target race to resize the item to.
