+# Azure Containerservice Module for Go
+
+[![PkgGoDev](https://pkg.go.dev/badge/github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/containerservice/armcontainerservicefleet)](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/containerservice/armcontainerservicefleet)
+
+The `armcontainerservicefleet` module provides operations for working with Azure Containerservice.
+
+[Source code](https://github.com/Azure/azure-sdk-for-go/tree/main/sdk/resourcemanager/containerservice/armcontainerservicefleet)
+
+# Getting started
+
+## Prerequisites
+
+- an [Azure subscription](https://azure.microsoft.com/free/)
+- Go 1.18 or above (You could download and install the latest version of Go from [here](https://go.dev/doc/install). It will replace the existing Go on your machine. If you want to install multiple Go versions on the same machine, you could refer this [doc](https://go.dev/doc/manage-install).)
+
+## Install the package
+
+This project uses [Go modules](https://github.com/golang/go/wiki/Modules) for versioning and dependency management.
+
+Install the Azure Containerservice module:
+
+```sh
+go get github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/containerservice/armcontainerservicefleet
+```
+
+## Authorization
+
+When creating a client, you will need to provide a credential for authenticating with Azure Containerservice.  The `azidentity` module provides facilities for various ways of authenticating with Azure including client/secret, certificate, managed identity, and more.
+
+```go
+cred, err := azidentity.NewDefaultAzureCredential(nil)
+```
+
+For more information on authentication, please see the documentation for `azidentity` at [pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity).
+
+## Client Factory
+
+Azure Containerservice module consists of one or more clients. We provide a client factory which could be used to create any client in this module.
+
+```go
+clientFactory, err := armcontainerservicefleet.NewClientFactory(<subscription ID>, cred, nil)
+```
+
+You can use `ClientOptions` in package `github.com/Azure/azure-sdk-for-go/sdk/azcore/arm` to set endpoint to connect with public and sovereign clouds as well as Azure Stack. For more information, please see the documentation for `azcore` at [pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azcore](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azcore).
+
+```go
+options := arm.ClientOptions {
+    ClientOptions: azcore.ClientOptions {
+        Cloud: cloud.AzureChina,
+    },
+}
+client, err := armcontainerservicefleet.NewClientFactory(<subscription ID>, cred, &options)
+```
+
+## Clients
+
+A client groups a set of related APIs, providing access to its functionality.  Create one or more clients to access the APIs you require using client factory.
+
+```go
+client := clientFactory.NewFleetsClient()
+```
+
+## Provide Feedback
+
+If you encounter bugs or have suggestions, please
+[open an issue](https://github.com/Azure/azure-sdk-for-go/issues) and assign the `Containerservice` label.
