 To use [natural keys] in vanilla Django, you need to define a `natural_key()` method on your Model class and a `get_natural_key()` method on the Manager class.  With *Django Natural Keys*, you can instead extend `NaturalKeyModel` and define one of the following:
 
- * A [`UniqueConstraint`](https://docs.djangoproject.com/en/3.2/ref/models/constraints/#uniqueconstraint) in `Meta.constraints` (recommended),
- * A tuple in [`Meta.unique_together`](https://docs.djangoproject.com/en/3.2/ref/models/options/#unique-together), or
- * A [model field](https://docs.djangoproject.com/en/3.2/ref/models/fields/#unique) (other than `AutoField`) with `unique=True`
+ * A [`UniqueConstraint`][UniqueConstraint] in `Meta.constraints` (recommended),
+ * A tuple in [`Meta.unique_together`][unique_together], or
+ * A [model field][unique] (other than `AutoField`) with `unique=True`
 
 The first unique constraint found will be treated as the natural key for the model, and all of the necessary functions for working with natural keys will automatically work.

 Note that the `natural_key_slug` may not behave as expected if any of the component values contain the delimiter character (`-` by default).  To mitigate this, you can set `natural_key_separator` on the model class to another character.
