-#### Getting Unique Models
-Sometimes you have relationship which has duplicate models in the result. In simple case you call `unique` on final Collection and that's all.
-
-But if you need unique records on DB level (for example for pagination) you can use this approach:
-
-```php
-// HasManyDeep relation Warehouse -> WarehousePosition -> Product
-$warehouse->products()
-    // GROUP BY target table primary key
-    ->groupBy("products.id")
-
-    // get underlying Builder without laravel_through_key in SELECT
-    ->getQuery()
-
-    // SELECT columns only from target table
-    ->select('products.*')
-    ->get();
-```
-
-Instead of `groupBy` you can call `distinct`. That should works too.
-
 #### Composite Keys
 
 If multiple columns need to match between two tables, you can define a composite key with the `CompositeKey` class.

+### Getting Unique Results
+
+Deep relationships with many-to-many segments can contain duplicate models in their results. If you want to get unique
+results, you can remove duplicates from the result collection:
+
+```php
+$uniqueComments = Country::find($id)->comments->unique();
+```
+
+If you need to remove duplicates in the query (e.g. for pagination), try adding `distinct()`:
+
+```php
+$uniqueComments = Country::find($id)->comments()->distinct()->get();
+```
+
+`distinct()` doesn't work for all cases. If it doesn't work for you, use `groupBy()` instead:
+
+```php
+$uniqueComments = Country::find($id)->comments()
+    ->getQuery()             // Get the underlying query builder
+    ->select('comments.*')   // Select only columns from the related table
+    ->groupBy('comments.id') // Group by the related table's primary key 
+    ->get();
+```

 ### Reversing Relationships
 
 You can define a `HasManyDeep`/`HasOneDeep` relationship by reversing an existing deep relationship
