+Locale - Default UoM
+====================
+
+This module adds a concept of a default unit of measure on languages, unique by
+unit category type.
+
+It also provides a method that can be used in fields to work from said defaults.
+
+Configuration
+=============
+
+Set default unit of measures in the `Languages` menu in settings.
+
+Usage
+=====
+
+Fields that want to implement the language default should use the provided
+method, such as in the below example:
+
+    class MyModel(models.Model):
+        _name = 'my.model'
+        time_uom_id = fields.Many2one(
+            string='Time Units',
+            comodel_name='uom.uom',
+            default=lambda s: s.env['res.lang'].default_uom_by_category('Time'),
+        )
