+# .NET Core
+
+This repository contains the class libraries for .NET Core. This is currently a
+work in progress, and does not currently contain the entire set of libraries
+that we plan on open sourcing. Make sure to watch this repository in order to be
+notified as we make changes to and expand it. Check out this [blog post] that
+explains our OSS strategy and road map in more detail.
+
+Today, it contains the following components:
+
+* **Immutable Collections**. A set of collection types that make it easy to keep
+  mutable state under control without sacrificing performance or memory
+  footprint. You can read more about them on [MSDN][immutable-msdn].
+
+* **ECMA-335 Metadata Reader**. This is a highly tuned low-level metadata reader
+  that allows [Roslyn] to parse assemblies.
+
+* **SIMD enabled vector types**. We've recently added a set of basic vector
+  types that leverage single instruction, multiple data (SIMD) CPU instructions.
+  See our [recent announcement][simd-post] for more details.
+
+* **XML**. This includes the DOM APIs such as the `XDocument` and `XmlDocument`
+  types, XLinq as well the corresponding XPath extension methods.
+
+More is coming soon. Stay tuned!

+# Developer Guide
+
+## Building, Testing, and Running
+
+You can build .NET Core either via the command line or by using Visual Studio.
+We currently only support building and running on Windows. Other platforms will
+come later.
+
+The command line build is invoked via
+
+```
+build.cmd
+```
+
+In order to build successfully, you must have Visual Studio 2013 or higher
+installed.
+
+### Running Tests
+
+We use the OSS testing framework [xUnit.net][xunit].
+
+Running the tests from the command line is as simple as invoking `build.cmd`.
+
+You can also run the tests from within Visual Studio. See [this page][xunit-runner]
+for more details on how to install the required test runner and how you can
+invoke the tests using Test Explorer.
+
+[xunit]: http://xunit.github.io/
+[xunit-runner]: https://xunit.codeplex.com/wikipage?title=HowToUseVs2012
+
+## Strong Name Signing
+
+All .NET Core binaries are strong named. In order for us to enable you to build
+binaries that have a matching identity we leverage a mechanism called
+*OSS signing*.
+
+OSS signing is essentially just [delay signing][delay-signing] the assembly
+except that the resulting assembly is marked as fully signed. This allows you to
+load the assembly in most contexts, or more precisely in any context that
+doesn't require validating the strong name identity. This means that you can't
+install OSS signed assemblies into the GAC nor can you use it in partial trust.
+
+OSS signing allows you to produce binaries that match the strong name identity
+of the official binaries as released by Microsoft without having to add skip
+verification entries to your machine.
+
+When running on the .NET Framework (desktop) we only support using OSS signed
+binaries for debugging and testing purposes. In other words, we don't guarantee
+that you can successfully load OSS signed assemblies in all scenarios that are
+required for production use.
+
+However, in the context of ASP.NET Core and .NET Native on Windows we support
+loading OSS signed binaries in production. But keep in mind that Microsoft
+doesn't support the binaries themselves -- we only support the ability to load
+them.
