 [ArrayFire](https://github.com/arrayfire/arrayfire) is a high performance library for parallel computing with an easy-to-use API. It enables users to write scientific computing code that is portable across CUDA, OpenCL and CPU devices. This project provides Lua bindings for the ArrayFire library.
 
-The wrapper is currently compliant with ArrayFire 3.2 API (and higher). If you find any bugs, please report them [here](https://github.com/arrayfire/arrayfire-lua/issues).
+The wrapper is currently compliant with ArrayFire 3.4 API (and higher). If you find any bugs, please report them [here](https://github.com/arrayfire/arrayfire-lua/issues).
 
 ## Example
 
-```lua
-local AF = require("arrayfire")
-
-AF.main(function()
-      local x = AF.randu(5, "f32")
-      AF.print("x", x)
-      AF.print("min of x", AF.min(x))
-      AF.print("max of x", AF.max(x))
-end)

 ### Building the Lua module
 
-**Windows**
-
-1. Launch `cmake-gui`. Set source and build directories.
-2. Press configure.
-3. Select `generator` as `Visual Studio 12 2013 Win64`.
-   - You can choose a different generator as long as it is Win64.
-4. Set `CMAKE_INSTALL_PREFIX` to a location of choice.
-5. Press generate. The generated visual studio solution file will be present in the build directory.
-6. Open the VS solution file and build the `INSTALL` project.
-
-**Linux / OSX**
-
-1. Make sure the environment variable `ArrayFire_DIR` is set to `/path/to/arrayfire/share/ArrayFire/cmake`.
-2. Create a build directory and `cd` into it.
-3. Run `cmake /path/to/arrayfire-lua/ -DCMAKE_INSTALL_PREFIX=package`.
-4. Run `make`
-
-### Setting up Lua paths
-
-**Windows**
-
-    > SET LUA_PATH=C:\path\to\install\location\arrayfire\?.lua;;
-    > SET LUA_CPATH=C:\path\to\install\location\?.dll;;
-    > lua.exe helloworld/helloworld.lua

-**Linux**
-
-    $ export LUA_PATH="/path/to/install/location/arrayfire/?.lua;;"
-    $ export LUA_CPATH="/path/to/install/location/?.so;;"
-    $ lua helloworld/helloworld.lua
-
+```
+cd /path/to/arrayfire-lua/
+luarocks make
+```
 
 You should now be good to go!
