+== # Compiling Iso2Mesh ==
+
+The default release of Iso2Mesh packages already contains pre-compiled
+binaries for a wide range of platforms (32/64bit Windows, 32/64bit Linux
+and Mac with 64bit Intel and 32 bit PowerPC CPUs). So, without needing 
+to recompile, Iso2Mesh can be executed out-of-box on MATLAB or GNU Octave.
+
+However, in the event that your operating system is not supported, or
+due to license restrictions, such as creating a release for various
+Linux distributions, you can recreate the mesh utility binaries under
+iso2mesh/bin folder by following the below commands:
+
+ git clone --recurse-submodules https://github.com/fangq/iso2mesh.git
+ cd iso2mesh
+ rm -rf bin/*.mex* bin/*.exe
+ cd tools
+ make clean
+ make
+
+This will download and recompile the below binaries in the bin folder:
+
+ cgalmesh
+ cgalsurf
+ cgalsimp2
+ jmeshlib
+ meshfix
+ tetgen1.5
+ cork
+
+Once these binary files are recreated, you can run all the major functionalities
+of Iso2Mesh. The gtsset and gtrefine tools are depreciated and replaced by 
+cork and tetgen.
+
+To compile the above external tools, the below tools must be pre-installed
+(tested on Ubuntu 14.04 LTS, if you use another Linux distribution, the package
+names might be different)
+
+ libcgal-dev
+ clang
+ cmake
+
+you can install these by
+
+ sudo apt-get install libcgal-dev clang cmake
+
+on Ubuntu.
