 This directory contains the C# Protocol Buffers runtime library.
 
+Warning: experimental!
+======================
+
+This code is still under significant churn. Unlike the original port,
+it only supports proto3 (but not *all* of proto3 yet) - there are no
+unknown fields or extensions, for example. protoc will (eventually)
+deliberately fail if it is asked to generate C# code for proto2
+messages other than descriptor.proto, which is still required for
+reflection. (It's currently exposed publicly, but won't be
+eventually.)
+
+Also unlike the original port, the new version embraces mutability -
+there are no builder types. We plan to add "freezing" operations as
+well as cloning, however.
+
 Usage
 =====
 
-The easiest way to use C# protocol buffers in your project is to use the [Google.ProtocolBuffers NuGet package](http://www.nuget.org/packages/Google.ProtocolBuffers/). This package is the legacy package for C# protocol buffers, but it will work fine with C# code generated by `protoc` if you use proto2 syntax (The API of the runtime library haven't changed so far).
+Use `protoc` with the `--csharp_out` option to generate C# files in the specified directory.
+Include these in your C# project, and add a reference to the `Google.Protobuf` project. Currently
+there is no NuGet package for this, but we will be building one as soon as the API is stable.
+
+Supported platforms
+===================
 
-*WARNING: If you specify `syntax = "proto3";` in your .proto files, the generated code won't necessarily work with the legacy NuGet package. So before we officially add proto3 support, always use `syntax = "proto2";` (the default) in your protos.*
+The runtime library is built as a portable class library, supporting:
 
-We will definitely release a new NuGet package for the runtime library in the future. The new runtime library WILL contain significant semantic, backwardly-incompatible changes in proto handling (mostly because we will be adding proto3 support and we will be using that oportunity to make some design changes). So keep in mind that you will need to regenerate your proto files and switch to a new NuGet package once the new version of runtime library becomes available.

 Building
 ========
 
-Open the `src/ProtocolBuffers.sln` solution in Visual Studio. Click "Build solution" to build the solution. You should be able to run the NUnit test from Test Explorer (you might need to install NUnit Visual Studio add-in).
+Open the `src/Google.Protobuf.sln` solution in Visual Studio. Click "Build solution" to build the solution. You should be able to run the NUnit test from Test Explorer (you might need to install NUnit Visual Studio add-in).
 
 Supported Visual Studio versions are VS2013 (update 4) and VS2015. On Linux, you can also use Monodevelop 5.9 (older versions might work fine).
 
-Proto2 & Proto3
-===============
-
-*WARNING: Only proto2 is supported for now, proto3 is under construction.*
-
-C# protocol buffers are currently under development and you should expect semantic, backward-incompatible changes in the future.
-
-Also, as of now, only proto2 is supported. Proto3 support for C# is currently in progress
-(both design & implementation) and you should not expect any of the proto3 features to work. 
-In fact, always use `syntax = "proto2";` in your .proto files for now, unless you are feeling like experimenting.

-    <description><![CDATA[
-Protocol Buffers is a binary serialization format and technology, released to the open source community by Google in 2008.  
-Its primary use is to produce small fast binary representations of a 'message' or object for serialization or transportation.
-There are various implementations of Protocol Buffers in .NET. This project is a fairly close port of the Google Java implementation.
-
-There are two main parts:
-
-tools/protoc.exe, which takes the textual representation of the protocol buffer and turns it into a binary representation for use with ProtoGen.exe.
-tools/ProtoGen.exe, which takes binary representations of protocol buffer descriptors (as generated by the "stock" protoc binary supplied by Google) and creates C# source code. This is only required at build time.
-
-lib/*/Google.ProtocolBuffers.dll, which is a supporting library. This is required at execution time.
-lib/*/Google.ProtocolBuffers.Serialization.dll, a supplementary library that provides extensions for reading and writing protocol buffers to xml, json, and others.

-    <description><![CDATA[
-Protocol Buffers is a binary serialization format and technology, released to the open source community by Google in 2008.  
-Its primary use is to produce small fast binary representations of a 'message' or object for serialization or transportation.
-There are various implementations of Protocol Buffers in .NET. This project is a fairly close port of the Google Java implementation.
-
-There are two main parts:
-
-tools/protoc.exe, which takes the textual representation of the protocol buffer and turns it into a binary representation for use with ProtoGen.exe.
-tools/ProtoGen.exe, which takes binary representations of protocol buffer descriptors (as generated by the "stock" protoc binary supplied by Google) and creates C# source code. This is only required at build time.
-
-lib/*/Google.ProtocolBuffersLite.dll, which is a supporting library. This is required at execution time.
-lib/*/Google.ProtocolBuffersLite.Serialization.dll, a supplementary library that provides extensions for reading and writing protocol buffers to xml, json, and others.

-# Script for uploading files to a Google Code project.
-#
-# This is intended to be both a useful script for people who want to
-# streamline project uploads and a reference implementation for
-# uploading files to Google Code projects.
-#
-# To upload a file to Google Code, you need to provide a path to the
-# file on your local machine, a small summary of what the file is, a
-# project name, and a valid account that is a member or owner of that
-# project.  You can optionally provide a list of labels that apply to
-# the file.  The file will be uploaded under the same name that it has
-# in your local filesystem (that is, the "basename" or last path
-# component).  Run the script with '--help' to get the exact syntax
-# and available options.
-#
-# Note that the upload script requests that you enter your
-# googlecode.com password.  This is NOT your Gmail account password!
-# This is the password you use on googlecode.com for committing to
-# Subversion and uploading files.  You can find your password by going
-# to http://code.google.com/hosting/settings when logged in with your
-# Gmail account. If you have already committed to your project's
-# Subversion repository, the script will automatically retrieve your
-# credentials from there (unless disabled, see the output of '--help'
-# for details).
-#
-# If you are looking at this script as a reference for implementing
-# your own Google Code file uploader, then you should take a look at
-# the upload() function, which is the meat of the uploader.  You
-# basically need to build a multipart/form-data POST request with the
-# right fields and send it to https://PROJECT.googlecode.com/files .
-# Authenticate the request using HTTP Basic authentication, as is
-# shown below.
