+Gravitino Hadoop catalog index includes the following chapters:
+
+- [Hadoop catalog overview and features](./hadoop-catalog.md): This chapter provides an overview of the Hadoop catalog, its features, capabilities and related configurations.
+- [Manage Hadoop catalog with Gravitino API](./manage-fileset-metadata-using-gravitino.md): This chapter explains how to manage fileset metadata using Gravitino API and provides detailed examples.

+
+### Hadoop catalog with cloud storage
+
+Apart from the above, you can also refer to the following topics to manage and access cloud storage like S3, GCS, ADLS, and OSS:
+
+- [Using Hadoop catalog to manage S3](./hadoop-catalog-with-s3.md). 
+- [Using Hadoop catalog to manage GCS](./hadoop-catalog-with-gcs.md). 
+- [Using Hadoop catalog to manage ADLS](./hadoop-catalog-with-adls.md).

 when creating a fileset, or follow the rules of the catalog/schema location if not specified.
 
 The value of `storageLocation` depends on the configuration settings of the catalog:
-- If this is a S3 fileset catalog, the `storageLocation` should be in the format of `s3a://bucket-name/path/to/fileset`.
-- If this is an OSS fileset catalog, the `storageLocation` should be in the format of `oss://bucket-name/path/to/fileset`.
 - If this is a local fileset catalog, the `storageLocation` should be in the format of `file:///path/to/fileset`.
 - If this is a HDFS fileset catalog, the `storageLocation` should be in the format of `hdfs://namenode:port/path/to/fileset`.
-- If this is a GCS fileset catalog, the `storageLocation` should be in the format of `gs://bucket-name/path/to/fileset`.
