+> **NOTE:** This repository is under heavy ongoing development and should be considered a preview. Vendoring your
+dependencies is always a good idea, but it is doubly important if you're consuming this library.
 
 # Installation
-
-- [Install Go 1.7](https://golang.org/dl/).
-
+- If you don't already have it, install [the Go Programming Language](https://golang.org/dl/).
 - Go get the SDK:
 
 ```
-$ go get -d github.com/Azure/azure-sdk-for-go
+$ go get -u 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.
+> **IMPORTANT:** We highly suggest vendoring Azure SDK for Go as a dependency. For vendoring dependencies, Azure SDK

-```
-$ cd your/project
-$ glide create
-$ glide install
-```
+# Versioning
+## SDK Versions
+The tags in this repository are based on, but do not conform to [SemVer.org's recommendations](http://semver.org/).
+For now, the "-beta" tag is an indicator that we are still in preview and still are planning on releasing some breaking
+changes.
+
+In repositories that are children of this one, [storage for example](https://github.com/Azure/azure-storage-go), we
+have adopted SemVer.org's recommendations.
+
+## Azure Versions
+Azure services _mostly_ do not use SemVer based versions. Rather, they use profiles identified by dates. One will often
+see this casually referred to as an "APIVersion". At the moment, our SDK only supports the most recent profiles. In
+order to lock to an API version, one must also lock to an SDK version. However, as discussed in 
+[#517](https://github.com/Azure/azure-sdk-for-go/issues/517), our objective is to reorganize and publish independent
+packages for each profile. In that way, we'll be able to have parallel support in a single SDK version for all
+APIVersions supported by Azure.

-# 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/)
