+- This is a port for Windows based on [Redis](https://github.com/antirez/redis).
+- We officially support the 64-bit version only. Although you can build the 32-bit version from source if desired.
+- You can download the latest unsigned binaries and the unsigned MSI installer from the [release page](http://github.com/MSOpenTech/redis/releases "Release page").
+- For releases prior to 2.8.17.1, the binaries can found in a zip file inside the source archive, under the bin/release folder.
+- Signed binaries are available through [NuGet](https://www.nuget.org/packages/Redis-64/) and [Chocolatey](https://chocolatey.org/packages/redis-64).
+- Redis can be installed as a Windows Service.

-## Redis 3.0 Branch
-
-- This is a port for Windows based on Redis 3.0.
-- There is support for the 64-bit version. We have dropped official support for the 32-bit version, though you can build it from source if desired.
-- The latest unsigned binaries are available from the [Release Page](http://github.com/MSOpenTech/redis/releases "Release page").
-- Signed binaries can be downloaded using Nuget and Chocolatey.
-- Redis on Windows uses a replacement for the UNIX fork() API that simulates the copy-on-write behavior using the system paging file.
+## Windows-specific changes
+- There is a replacement for the UNIX fork() API that simulates the copy-on-write behavior using a memory mapped file on 2.8. Version 3.0 is using a similar behavior but dropped the memory mapped file in favor of the system paging file.
+- In 3.0 we switch the default memory allocator from dlmalloc to jemalloc that is supposed to do a better job at managing the heap fragmentation.
 - Because Redis makes some assumptions about the values of file descriptors, we have built a virtual file descriptor mapping layer. 
-- Redis on Windows can be installed as a Windows Service.

 ## How to build Redis using Visual Studio
 
-You can use the free [Visual Studio Community edition](http://www.visualstudio.com/products/visual-studio-community-vs). If you use Microsoft Visual Studio 2013 (standard), make sure you have updated to Update 5, otherwise you will get a " illegal use of this type as an expression" error.

 - Open the solution file msvs\redisserver.sln in Visual Studio, select a build configuration (Debug or Release) and target (x64) then build.

+To run the Redis test suite some manual work is required:
 
 - The tests assume that the binaries are in the src folder. Use mklink to create a symbolic link to the files in the msvs\x64\Debug|Release folders. You will
   need symbolic links for src\redis-server, src\redis-benchmark, src\redis-check-aof, src\redis-check-dump, src\redis-cli, and src\redis-sentinel.
 - The tests make use of TCL. This must be installed separately.
+- To run the cluster tests against 3.0, Ruby On Windows is required.
 - To run the tests you need to have a Unix shell on your machine, or MinGW tools in your path. To execute the tests, run the following command: 
   "tclsh8.5.exe tests/test_helper.tcl --clients N", where N is the number of parallel clients . If a Unix shell is not installed you may see the 
   following error message: "couldn't execute "cat": no such file or directory".
-- By default the test suite launches 16 parallel tests, but some of the tests may fail when the number of clients is greater than 2.
