+Azure Resource Manager ManagedServices client library for Java.
+
+This package contains Microsoft Azure SDK for ManagedServices Management SDK. The specification for ManagedServices. Package tag package-2020-02-preview. For documentation on how to use this package, please see [Azure Management Libraries for Java](https://aka.ms/azsdk/java/mgmt).

+## We'd love to hear your feedback
+
+We're always working on improving our products and the way we communicate with our users. So we'd love to learn what's working and how we can do better.
+
+If you haven't already, please take a few minutes to [complete this short survey][survey] we have put together.
+
+Thank you in advance for your collaboration. We really appreciate your time!
+
+## Documentation
+
+Various documentation is available to help you get started
+
+- [API reference documentation][docs]
+
+## Getting started
+
+### Prerequisites
+
+- [Java Development Kit (JDK)][jdk] with version 8 or above
+- [Azure Subscription][azure_subscription]
+
+### Adding the package to your product
+
+[//]: # ({x-version-update-start;com.azure.resourcemanager:azure-resourcemanager-managedservices;current})
+```xml
+
+    com.azure.resourcemanager
+    azure-resourcemanager-managedservices
+    1.0.0-beta.1
+
+```
+[//]: # ({x-version-update-end})
+
+### Include the recommended packages
+
+Azure Management Libraries require a `TokenCredential` implementation for authentication and an `HttpClient` implementation for HTTP client.
+
+[Azure Identity][azure_identity] package and [Azure Core Netty HTTP][azure_core_http_netty] package provide the default implementation.
+
+### Authentication
+
+By default, Azure Active Directory token authentication depends on correct configure of following environment variables.
+
+- `AZURE_CLIENT_ID` for Azure client ID.
+- `AZURE_TENANT_ID` for Azure tenant ID.
+- `AZURE_CLIENT_SECRET` or `AZURE_CLIENT_CERTIFICATE_PATH` for client secret or client certificate.
+
+In addition, Azure subscription ID can be configured via environment variable `AZURE_SUBSCRIPTION_ID`.
+
+With above configuration, `azure` client can be authenticated by following code:
+
+```java
+AzureProfile profile = new AzureProfile(AzureEnvironment.AZURE);
+TokenCredential credential = new DefaultAzureCredentialBuilder()
+    .authorityHost(profile.getEnvironment().getActiveDirectoryEndpoint())
+    .build();
+ManagedServicesManager manager = ManagedServicesManager
+    .authenticate(credential, profile);
+```
+
+The sample code assumes global Azure. Please change `AzureEnvironment.AZURE` variable if otherwise.
+
+See [Authentication][authenticate] for more options.
+
+## Key concepts
+
+See [API design][design] for general introduction on design and key concepts on Azure Management Libraries.
