+Configuration
+=============
+
+Enable unit of measure role
+---------------------------
+
+1. Go to Settings > Users & Companies > Users
+2. Create or edit a user
+3. Find the Manage Multiple Units of Measure role and select it
+4. Save
+
+|ROLE_UOM_IN_USER|
+
+Other option:
+
+1. Go to Settings
+2. Option Inventory
+3. Find the option Units of Measure and select it
+4. Save
+

+
+Usage
+=====
+
+Add Uom Reference
+-----------------
+
+1. Go to Inventory > Configuration > Product UOM Reference
+2. Add a new item
+3. Save
+
+|CREATE_REFERENCE|
+
+Configure Uom Reference in Product
+----------------------------------
+
+1. Go to Inventory > Products > Products
+2. Create a new product
+3. Select a reference unit. Note that only units whose initial unit of
+   measurement matches the product's unit of measurement will be
+   displayed
+4. Save
+
+|CONFIGURE_REFERENCE_PRODUCT|
+
+Print labels with Uom Reference
+-------------------------------
+
+1. Follow the steps `Configure Uom Reference in
+   Product <#configure-uom-reference-in-product>`__
+
+2. Press the Print labels button and select the type of label you want
+   to print
+
+3. Press the button Confirm
+
+4. Upon confirmation, the product label is generated, in which the price
+   of the reference unit is shown below the product price, taking into
+   account the ratio configured in `Add Uom
+   Reference <#add-uom-reference>`__.
+
+   Example:
+
+   - Price based on initial unit of measure (kg): $100 per kg
+   - Reference unit of measure ratio: 2.0
+   - Price based on reference unit of measure (lb): $50 per lb
