 You can use the credentials and the URL now to configure remote storage for your application with the help of [this document](../../ecommerce-applications/magento-2/how-to-configure-remote-storage-for-magento-2-x.md).
 
+### Managing objects in object storage
+
+You can manage your objects using the `hypernode-object-storage objects` subcommand.
+It supports all common operations--listing, copying, moving, and deleting files--while also allowing you to sync files in the background and monitor the progress of an ongoing sync.
+
+```console
+app@testhypernode ~ # hypernode-object-storage objects --help
+usage: hypernode-object-storage objects [-h] {sync,cp,ls,mv,rm,show} ...
+
+Manage objects in object storage
+
+positional arguments:
+  {sync,cp,ls,mv,rm,show}
+    sync                Synchronize files between a local directory and an object storage location
+    cp                  Copy a file or object from one location to another
+    ls                  List objects in an S3 bucket or folder
+    mv                  Move or rename a file or object
+    rm                  Delete an object from S3
+    show                Display the current status of an ongoing sync process
+
+options:
+  -h, --help            show this help message and exit
+```
+
+It is important to note that `hypernode-object-storage objects` supports all optional flags available in `aws s3`, allowing you to customize its behavior for advanced configurations.
+
+#### Syncing files and monitoring progress
+
+Syncing files between your local directory and object storage is simple. Run the following command:
+
+```console
+app@testhypernode ~ # hypernode-object-storage objects sync /example/local/path/ s3://example/bucket/uri/
+Syncing objects from /example/local/path/ to s3://example/bucket/uri/...
+Sync process started with PID 1234 in the background.
+```
+
+The `sync` operation runs in the background, and you can monitor its progress by using the `show` command, for example:
+
+```console
+app@testhypernode ~ # hypernode-object-storage objects show 1234
+Completed 9.7 GiB/~30.0 GiB (118.2 MiB/s) with ~5 file(s) remaining (calculating...)
+```
+
+If you run the `show` command after the sync operation has finished, you’ll see output like this:
+
+```console
+app@testhypernode ~ # hypernode-object-storage objects show 1234
+Process 1234 does not exist anymore
+```
+
