 ### Fixtures
-This bundle supports doctrine style fixtures, to create one you will need to create a php class in your bundle '/DataFixtures/Mongo' directory for Example 'src/AppBundle/DataFixtures/Mongo/LoadTaskDataFixture.php'
-
-Note: This class must implement at least the MongoFixtureInterface, if you need container support you can extend AbstractContainerAwareFixture to use the getContainer method.

+#### Ordering
+Since [0.6.6](https://github.com/facile-it/mongodb-bundle/releases/tag/0.6.6) it's possibile to specify the order by 
+which the fixtures are loaded.
+Make sure it implements `OrderedFixtureInterface`.
+Fixtures with lower values of `getOrder` will be loaded first.
