 * This driver uses the [MongoDB TTL indexes](https://docs.mongodb.com/manual/core/index-ttl/) meaning when a session key expires it will be automatically deleted. So no need for garbage collection implementation.
 * This way, the collection's size will remain around the size you expect and won't get falsely filled with unused data.
-* The package automatically adds a migration which creates the index.

-Warning
--------
-
-This session driver is not compatible with other session drivers, because it uses its all table structure.
-If you are using another mongodb session driver at the moment make sure you set a new collection for this one.
+* The package automatically adds a migration which creates the index. If you change the name of the `session.table` you should rerun the ttl index creation command `php artisan mongodb:session:index`.
 
 Enjoy!
