+## Replicate Adapter
+You must require additional library `composer require league/flysystem-replicate-adapter`
+
+The ReplicateAdapter facilitates smooth transitions between adapters, allowing an application to stay functional and migrate its files from one adapter to another. The adapter takes two other adapters, a source and a replica. Every change is delegated to both adapters, while all the read operations are passed onto the source only.
