+Enabling the FIFO removal strategy
+==================================
+
+Lots and serial numbers differentiate identical products and track information like arrival or
+expiration dates. To enable this feature, navigate to :menuselection:`Inventory --> Configuration
+--> Settings`. Under the :guilabel:`Traceability` section, check the box beside :guilabel:`Lots &
+Serial Numbers`.

+.. image:: fifo/enable-lots-serial-numbers.png

+
+Enable tracking by lots or serial numbers
+-----------------------------------------
+
+Next, ensure the intended product is tracked by lots or serial numbers by navigating to the product
+form through :menuselection:`Inventory --> Products --> Products` and selecting the desired product.
+On the product form, open the :guilabel:`General Information` tab and select the check box next to
+the :guilabel:`Track Inventory` field, then select either :guilabel:`By Unique Serial Number` or
+:guilabel:`By Lots`.
+
+.. image:: fifo/track-by-serial-number.png
+   :alt: Enable tracking by serial number.
+
+Assigning lots and serial numbers
+---------------------------------
+
+After enabling the features, assign lot or serial numbers to products using an :doc:`inventory
+adjustment <../../warehouses_storage/inventory_management/count_products>` or :ref:`during
+reception <inventory/product_management/assign-lots>`.
+
+Setting removal strategies
+--------------------------
+
+After lot or serial numbers have been assigned, set the removal strategy on the product category or
+storage location.

+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, specify :guilabel:`First In First Out (FIFO)`.
