-##### Configuring S3 Adapter
+##### Configuring File Adapters
+Parse Server allows developers to choose from several options when hosting files: the `GridStoreAdapter`, which backed by MongoDB; the `S3Adapter`, which is backed by [Amazon S3](https://aws.amazon.com/s3/); or the `GCSAdapter`, which is backed by [Google Cloud Storage](https://cloud.google.com/storage/).
 
-You can use the following environment variable setup the S3 adapter
+`GridStoreAdapter` is used by default and requires no setup, but if you're interested in using S3 or GCS, additional configuration information is available below.
