+// Functions in this file support the public tag_set API, as well as
+// encoding/decoding tag_sets as part of context propagation across
+// RPC's. The overall requirements (in approximate priority order) for the
+// tag_set representations:
+// 1. Efficient conversion to/from wire format
+// 2. Minimal bytes used on-wire
+// 3. Efficient tag set creation
+// 4. Efficient lookup of value for a key
+// 5. Efficient lookup of value for an index (to support iteration)
+// 6. Minimal memory footprint
+//
+// Notes on tradeoffs/decisions:
+// * tag includes 1 byte length of key, as well as nil-terminating byte. These
+//   are to aid in efficient parsing and the ability to directly return key
+//   strings. This is more important than saving a single byte/tag on the wire.
+// * The wire encoding uses only single byte values. This eliminates the need
+//   to handle endian-ness conversions. It also means there is a hard upper
+//   limit of 255 for both CENSUS_MAX_TAG_KV_LEN and CENSUS_MAX_PROPAGATED_TAGS.
+// * Keep all tag information (keys/values/flags) in a single memory buffer,
+//   that can be directly copied to the wire.14
+// * Binary tags share the same structure as, but are encoded separately from,
+//   non-binary tags. This is primarily because non-binary tags are far more
+//   likely to be repeated across multiple RPC calls, so are more efficiently
+//   cached and compressed in any metadata schemes.
+// * all lengths etc. are restricted to one byte. This eliminates endian
+//   issues.

+gRPC Native Nuget package
+=========================
+
+Prerequisites
+-------------
+
+NuGet binary
+
+Building the package
+--------------------
+
+To build the native package, you need precompiled versions
+of grpc_csharp_ext library artifacts for Windows, Linux and Mac.
+In the normal gRPC release process, these are built by a Jenkins
+job and they are copied to the expected location before building
+the native nuget package is attempted.
+
+See tools/run_tests/build_artifacts.py for more details how
+precompiled artifacts are built.
+
+When building the native NuGet package, ignore the "Assembly outside lib folder"
+warnings (the DLLs are not assemblies, they are native libraries).

 -------------
 
 - Ruby 2.x. The gRPC API uses keyword args.
-- [homebrew][] on Mac OS X.  These simplify the installation of the gRPC C core.
 
 INSTALLATION
 ---------------
 
-**Linux (Debian):**
-
-Add [Debian jessie-backports][] to your `sources.list` file. Example:
-
-```sh
-echo "deb http://http.debian.net/debian jessie-backports main" | \
-sudo tee -a /etc/apt/sources.list
-```
-
-Install the gRPC Debian package
-
-```sh
-sudo apt-get update
-sudo apt-get install libgrpc-dev
-```
-
-Install the gRPC Ruby package
+**Linux and Mac OS X:**
 
 ```sh
 gem install grpc
 ```
 
-**Mac OS X**
-
-Install [homebrew][]. Run the following command to install gRPC Ruby.
-```sh
-$ curl -fsSL https://goo.gl/getgrpc | bash -s ruby
-```
-This will download and run the [gRPC install script][], then install the latest version of gRPC Ruby gem.  It also installs Protocol Buffers compiler (_protoc_) and the gRPC _protoc_ plugin for ruby.
-

-gRPC Native Nuget package
-=========================
-
-Prerequisites
--------------
-Multiple versions of VS installed to be able to build all the targets:
-* Visual Studio 2015
-* Visual Studio 2013
-* Visual Studio 2010 (you might need SP1 to prevent LNK1123 error)
-
-NuGet binary
-
-Building the package
---------------------
-
-Build all flavors of gRPC C# extension and package them as a NuGet package.
-```
-buildall.bat
-
-nuget pack grpc.native.csharp.nuspec
-```
-
-When building the NuGet package, ignore the "Assembly outside lib folder" warnings (they DLLs are not assemblies, they are native libraries).
