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."

+
+## Use from Crates.io
+
+To use the rust bindings for ArrayFire from crates.io, the following requirements are to be met
+first.
+
+1. [Download and install ArrayFire binaries](https://arrayfire.com/download) based on your operating
+   system.
+2. Set the evironment variable `AF_PATH` to point to ArrayFire installation root folder.
+3. Make sure you add the path to library files to your path environment variables.
+    - On Linux & ODX: do `export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$AF_PATH/lib`
+    - On Windows: Add `%AF_PATH%\lib` to your PATH environment variable.
+4. Add `arrayfire = "3.2.0"` to the dependencies section of your project's Cargo.toml file.
+
+Once step (4) is over, you should be able to use ArrayFire in your Rust project. If you find any bugs, please report them [here](https://github.com/arrayfire/arrayfire-rust/issues).

+## Build from Source
 
 Edit [build.conf](build.conf) to modify the build flags. The structure is a simple JSON blob. Currently Rust does not allow key:value pairs to be passed from the CLI. To use an existing ArrayFire installation modify the first three JSON values. You can install ArrayFire using one of the following two ways.
