 Using `npm` you can upgrade to the latest stable version of AutoRest:
 
-## AutoRest 2.0 Branch
-
-AutoRest is making a a few structural changes, along with eliminating some deprecated legacy behavior.
-
-Notable changes in this branch:
-- Bumping required node.js version to 7.10 or greater. (Will add checks in to ensure that this is the case)<br> This enables us to target the `ES2017` javascript standard, vastly simplifying compiled code and has significant performance benefits. 
-- Bumping Dotnet/CLI SDK and Runtime to 2.0
-- Updated bootstrapper that implements use-extension
-- Moving common TypeScript code into the Perks.Node project so that they can be built and reused independently of building AutoRest.
-- Removing all remaining Legacy CLI features, standardizing on the `--switch` format for all cmdline operations

+### Supported Platforms
 
-Other Linux platforms *might* work -- if the platform is listed https://github.com/Azure/autorest/releases/tag/dotnet-runtime-1.0.4 -- there is a fairly good chance that it'll work. As more testing is completed, we'll ensure that we update the status here.
+While AutoRest itself runs on NodeJS, some generators use the .NET Core 2.0 runtime, which is the most limiting factor.
+See [dotnet/core/release-notes/2.0/2.0-supported-os.md](https://github.com/dotnet/core/blob/master/release-notes/2.0/2.0-supported-os.md) for a list of supported platforms.
