+
+### Changes
+
+- Moved the arm/authorization, arm/features, arm/resources, and arm/subscriptions packages under a new, resources, package (to reflect the corresponding Swagger structure)
+- Added a new arm/authoriation (2015-07-01) package
+- Added a new arm/cdn (2015-06-01) package
+- Added a new arm/intune (2015-01-14-preview) package
+- Udated arm/network (2015-06-01)
+- Added a new arm/notificationhubs (2014-09-01) package
+- Updated arm/scheduler (2016-01-01) package

+
+## `v0.3.0-beta`
+
+- Corrected unintentional struct field renaming and client renaming in v0.2.0-beta
+
+-----
+
+## `v0.2.0-beta`
+
+- Added support for DNS, Redis, and Web site services
+- Updated Storage service to API version 2015-06-15
+- Updated Network to include routing table support

+
+------
+
+## `v0.1.1-beta`
+
+- Improves the UserAgent string to disambiguate arm packages from others in the SDK
+- Improves setting the http.Response into generated results (reduces likelihood of a nil reference)
+- Adds gofmt, golint, and govet to Travis CI for the arm packages
+

+
+------
+
+## v0.1.0-beta
+
+This release addresses the issues raised against the alpha release and adds more features. Most
+notably, to address the challenges of encoding JSON
+(see the [comments](https://github.com/Azure/go-autorest#handling-empty-values) in the
+[go-autorest](https://github.com/Azure/go-autorest) package) by using pointers for *all* structure
+fields (with the exception of enumerations). The
+[go-autorest/autorest/to](https://github.com/Azure/go-autorest/tree/master/autorest/to) package
+provides helpers to convert to / from pointers. The examples demonstrate their usage.
+
+Additionally, the packages now align with Go coding standards and pass both `golint` and `govet`.
+Accomplishing this required renaming various fields and parameters (such as changing Url to URL).
+
+##### Changes
+
+- Changed request / response structures to use pointer fields.
+- Changed methods to return `error` instead of `autorest.Error`.
+- Re-divided methods to ease asynchronous requests.
+- Added paged results support.
+- Added a UserAgent string.
+- Added changes necessary to pass golint and govet.
+- Updated README.md with details on asynchronous requests and paging.
+- Saved package dependencies through Godep (for the entire SDK).
+
+##### Fixed Issues:
+
+- https://github.com/Azure/azure-sdk-for-go/issues/205
+- https://github.com/Azure/azure-sdk-for-go/issues/206

+
+## v0.1.0-alpha
+
+This release introduces the Azure Resource Manager packages generated from the corresponding
+[Swagger API](http://swagger.io) [definitions](https://github.com/Azure/azure-rest-api-specs).

+[About Storage](/storage/README.md)
+
+- [storage](/storage)
+
+# Installation
+
+- [Install Go 1.7](https://golang.org/dl/).
+
+- Go get the SDK:
+
+```
+$ go get -d github.com/Azure/azure-sdk-for-go
+```
+
+> **IMPORTANT:** We highly suggest vendoring Azure SDK for Go as a dependency. For vendoring dependencies, Azure SDK for Go uses [glide](https://github.com/Masterminds/glide). If you haven't already, install glide. Navigate to your project directory and install the dependencies.
+
+```
+$ cd your/project
+$ glide create
+$ glide install
+```

+# Azure Storage SDK for Go
+
+The `github.com/Azure/azure-sdk-for-go/storage` package is used to perform operations in Azure Storage Service. To manage your storage accounts (Azure Resource Manager / ARM), use the [github.com/Azure/azure-sdk-for-go/arm/storage](../arm/storage) package. For your classic storage accounts (Azure Service Management / ASM), use [github.com/Azure/azure-sdk-for-go/management/storageservice](../management/storageservice) package.
+
+This package includes support for [Azure Storage Emulator](https://azure.microsoft.com/documentation/articles/storage-use-emulator/)
