+    :summary: View, add, and remove the item styles a civ can make.
+    :tags: adventure fort gameplay
+
+Civs pick randomly from a pool of item types at worldgen, so not every civ gets
+togas, whips, or high boots. This lists every weapon, armor, clothing, ammo,
+tool, toy, trap component, siege ammo, and instrument in the raws, marks the
+ones your civ knows how to make, and lets you toggle them.
+
+Unlike `add-recipe`, you can see what your civ already knows, and you can take a
+style away again. Removing a style only stops new orders; items already made are
+unaffected.
+
+Pick a category on the left, or search the ``All`` list, then hit :kbd:`Enter` to
+toggle a row. Changes are saved with the fortress.
+
+Rows are marked ``native`` if the style came from your civ's raws, ``exotic`` if
+it did not, ``gen`` for procedurally generated items, and ``xN`` if the style is
+listed more than once, which repeated `add-recipe` runs will do.
+:kbd:`Ctrl`:kbd:`D` removes duplicates.
