 description   = "ArrayFire is a high performance software library for parallel computing with an easy-to-use API. Its array based function set makes parallel programming simple. ArrayFire's multiple backends (CUDA, OpenCL and native CPU) make it platform independent and highly portable. A few lines of code in ArrayFire can replace dozens of lines of parallel computing code, saving you valuable time and lowering development costs. This crate provides Rust bindings for ArrayFire library."

 ## Supported platforms
 
-Currently, only Linux and OSX. With Rust 1.4(MSVC binary), we soon expect to get the Windows support available.
+- Linux and OSX: The bindings have been tested with Rust 1.x.
+- Windows: Rust 1.5 (MSVC ABI) is the first version that works with our bindings and ArrayFire library(built using MSVC compiler).
 
-## Use from Crates.io
+We recommend using Rust 1.5 and higher.

 To use the rust bindings for ArrayFire from crates.io, the following requirements are to be met
 first.
