+POS interface.
+
+To manage PoS categories, go to :menuselection:`Point of Sale --> Configuration --> PoS Product
+Categories`. To add a new category, click :guilabel:`Create`. Then, name it in the
+:guilabel:`Category Name` field.
+
+To associate a category with a parent category, fill in the :guilabel:`Parent Category` field. A
+parent category groups one or more child categories.
