+# Cloud Storage Batch Operations Sample
+
+These samples demonstrate how to interact with the [Google Cloud Storage Batch Operations API][Storage Batch Operations] from C# and
+the .NET client libraries to call the Storage Batch Operations API.
+
+The samples require [.NET 8][.NET].That means using
+[Visual Studio 2022](https://www.visualstudio.com/), or the command line.
+
+## Setup
+
+1.  Set up a [.NET development environment](https://cloud.google.com/dotnet/docs/setup).
+
+2.  Enable APIs for your project.
+    [Click here][enable-api]
+    to visit Cloud Platform Console and enable the Google Cloud Storage Batch Operations API.
