 The *Least Packages* removal strategy fulfills an order by opening the fewest number of packages,
 which is ideal for maintaining organized stock without needing to open multiple boxes.

+
+   To understand how the removal strategy works, consider the following example, featuring a
+   warehouse that stores packages of flour in bulk packages of `100 kg`.
+
+   To minimize moisture and prevent possible loss of product due to spillage and repacking, the
+   least packages removal strategy is used to fill the order by opening the fewest packages of
+   flour, instead of opening multiple packages.
+
    A package of `100 kg` of flour is depleted to `54 kg` after fulfilling some orders. There are
    other packages of `100 kg` in stock.
 
-   #. When an order for `14 kg` of flour is placed, the package of `54 kg` is selected.
-   #. When an order for *more* than `54 kg` of flour is placed, an unopened `100 kg` package is used
-      to fulfill the order. While this temporarily results in two open packages, these open packages
-      are prioritized in the next picking.
+   When an order for `14 kg` of flour is placed, the package of `54 kg` is selected, leaving `40 kg`
+   of flour in the bag. Another order for `80 kg` of flour is placed. An unopened `100 kg` package
+   is used to fulfill the order.
+
+   While this temporarily results in two open packages, one for `40 kg` and another for `20 kg`,
+   these open packages are prioritized in the next pickings that are those sizes or smaller.
+
+Enabling the least packages removal strategy
+============================================
+
+A *package* is a physical container holding one or more products. Packages can also be used to store
+items in bulk.
+
+The packages feature is used to group products together and is required for the *least packages*
+removal strategy.
+
+Navigate to :menuselection:`Inventory app --> Configuration --> Settings` and in the
+:guilabel:`Operations` section, select the check box for the :guilabel:`Packages` feature.
+
+Store products in packages
+--------------------------
+
+First, products are received either in packages or individually. Next, the received products are
+stored in packages created :ref:`during a transfer <inventory/warehouses_storage/pack>`.
+
+Set the removal strategy
+------------------------
+
+After you have configured your product inventory, set the removal strategy on the :ref:`storage
+location <inventory/warehouses_storage/lp-location>` or :ref:`product category
+<inventory/warehouses_storage/lp-category>`.
+
+.. _inventory/warehouses_storage/lp-location:
+
+On the storage location
+~~~~~~~~~~~~~~~~~~~~~~~
+
+To set a removal strategy on a storage location, you must first enable a couple settings in the
+**Inventory** configuration settings. Open :menuselection:`Inventory app --> Configuration -->
+Settings`, and in the :guilabel:`Warehouse` section, enable :guilabel:`Storage Locations` and
+:guilabel:`Multi-Step Routes`.
+
+Next, open :menuselection:`Inventory app --> Configuration --> Locations`. Open an existing location
+or create a new location. On the location form, under the :guilabel:`Logistics` heading, set
+the :guilabel:`Removal Strategy`. to :guilabel:`Least Packages`
+
+.. image:: least_packages/location-removal-strategy.png
+   :alt: Set Least Packages as the location's removal strategy.
+
+.. _inventory/warehouses_storage/lp-category:
+
+On the product category
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Configure removal strategies on product categories by going to :menuselection:`Inventory app -->
+Configuration --> Categories` and selecting the intended product category. Next, in the
+:guilabel:`Force Removal Strategy` field, select :guilabel:`Least Packages`.
+
+.. image:: least_packages/category-removal-strategy.png
+   :alt: Set Least Packages as the category's removal strategy.
+
+.. important::
+   When there are different removal strategies applied on both the location and product category for
+   a product, the value set on the :guilabel:`Force Removal Strategy` field set on a product
+   category form is applied as top priority.
+
+   For example, flour is stored in 100-kilogram packages. It is stored in a location with other
+   heavy items. To minimize how far pickers have to walk, the location uses the :doc:`closest
+   location removal strategy <closest_location>`. To further optimize the picking time, and to
+   reduce the number of packages opened during picking, the flour's product category, `Baking
+   Materials`, uses the least packages removal strategy.

-Measure` field, located on the product form, is set to `kg`. The product is stored in packages of
-`100 kg`, with one remaining package containing `54 kg`. The product category's :guilabel:`Force

 .. tip::
-   To check the product's on-hand stock, navigate to the product form, and click the :guilabel:`On
