-### Libraries
+Note that these examples are *not* exhaustive and you can use GCS in other places as well, including your [high availability setup]({{< ref "docs/deployment/ha/overview" >}}) or the [EmbeddedRocksDBStateBackend]({{< ref "docs/ops/state/state_backends" >}}#the-rocksdbstatebackend); everywhere that Flink expects a FileSystem URI.
+
+### GCS File System plugin
+
+Flink provides the `flink-gs-fs-hadoop` file system to write to GCS.
+This implementation is self-contained with no dependency footprint, so there is no need to add Hadoop to the classpath to use it.
 
-You must include the following jars in Flink's `lib` directory to connect Flink with gcs:
+`flink-gs-fs-hadoop` registers a `FileSystem` wrapper for URIs with the *gs://* scheme. It uses Google's [gcs-connector](https://mvnrepository.com/artifact/com.google.cloud.bigdataoss/gcs-connector) Hadoop library to access GCS. It also uses Google's [google-cloud-storage](https://mvnrepository.com/artifact/com.google.cloud/google-cloud-storage) library to provide `RecoverableWriter` support.

+This file system supports being used in [file sinks]({{< ref "docs/content/docs/connectors/datastream/filesystem.md" >}}).

Review comment:
       We've recently renamed the File Sink to FileSystem. 
   
   ```suggestion
   This file system can be used with the [FileSystem connector]({{< ref "docs/content/docs/connectors/datastream/filesystem.md" >}}).
   ```
