-This package is an initial attempt to create a rockspec file that will build and install a SimpleITK module for Lua via [LuaRocks](https://luarocks.org), a package manager for Lua modules.  [SimpleITK](http://www.simpleitk.org) is a simplified programming layer on top of the [Insight Segmentation and Registration Toolkit](https://itk.org) (ITK).  ITK is an open-source, cross-platform system that provides developers with an extensive suite of software tools for image analysis.

 ## Building the SimpleITK Lua module
-Building the module requires Lua v5.1.5, LuaRocks v2.2 and [CMake](https://cmake.org) v3.  Because SimpleITK is built as a CMake-type build in LuaRocks, this module will only build on Linux and OS X.  Currently cmake builds are not supported on Windows in Luarocks.
+Building the module requires Lua v5.1.5, LuaRocks v2.2 and [CMake](https://cmake.org) v3.10.  Because SimpleITK is built as a CMake-type build in LuaRocks, this module will only build on Linux and OS X.  Currently cmake builds are not supported on Windows in Luarocks.
 
 Building SimpleITK requires a sizeable amount of computing power.  We recommend a multi-core system with a sizable amount of memory.  Also, to facilitate multi-processing, the environment variable MAKEFLAGS should be set to something like "-jN", where N is the number of cores.  For example, on an 8 core system, use the following:
 ```
   export MAKEFLAGS="-j8"
 ```  
 Build the SimpleITK Lua module with the following command:
 ```
-  luarocks install simpleitk-1.0-0.rockspec
+  luarocks install simpleitk-1.2-0.rockspec
 ```
 ## SimpleDerivative.lua example
 When building the module, an example progam is installed into the SimpleITK rock, [SimpleDerivative.lua](https://github.com/SimpleITK/SimpleITK/blob/master/Examples/Lua/SimpleDerivative.lua).  It is copied from the [SimpleITK repository](https://github.com/SimpleITK/SimpleITK) .
 
-The program demonstrates a basic progam that uses SimpleITK to create an image of a Gaussian, and then performs some operations on that image.  First it applies the first derivative in the X direction on the gaussian, then it rescales the pixel intensities and converts the pixel types from float32 to uint8.  Finally the result is written out as a PNG file, and the image is displayed with the [Show function](https://itk.org/SimpleITKDoxygen/html/namespaceitk_1_1simple.html#ac8416e6e7f02dedfe8373b83dbea411d), which invokes [Fiji/ImageJ](http://fiji.sc).

 ## Custom builds
-The rockspec in this package is tied to a particular version of SimpleITK.  So simpleitk-1.0-0.rockspec will build SimpleITK v1.0.
