+NVIDIA Flex - 1.2.0
+===================
+
+Flex is a particle-based simulation library designed for real-time applications.
+Please see the programmer's manual included in this release package for more information on
+the solver API and usage.
+
+Supported Platforms
+-------------------
+
+* Windows 32/64 bit (CUDA, DX11, DX12)
+* Linux 64 bit (CUDA, tested with Ubuntu 16.04 LTS and Mint 17.2 Rafaela)
+
+Requirements
+------------
+
+A D3D11 capable graphics card with the following driver versions:
+
+* NVIDIA GeForce Game Ready Driver 372.90 or above
+* AMD Radeon Software Version 16.9.1 or above
+* Intel® Graphics Version 15.33.43.4425 or above
+
+To build the demo at least one of the following is required:
+
+* Microsoft Visual Studio 2013
+* Microsoft Visual Studio 2015
+* g++ 4.6.3 or higher
+
+And either: 
+
+* CUDA 9.1.85 toolkit
+* DirectX 11/12 SDK
+
+Demo 
+====
+
+Use the `run_cuda.bat` or `run_d3d.bat` files to launch the demo.
+
+Notes 
+-----
+
+* Some scenes also have fluid emitters that can be started using 'space'
+* For running the Linux binaries you will need to export the path to where the CUDA run time libraries are
+  For example, you may add to your .bashrc file the following:
+
+      export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
+
+
+Command Line Options
+--------------------
+
+The following commands may be passed to the demo application to modify behavior:
+
+    -fullscreen=wxh  Start fullscreen e.g.: -fullscreen=1280x720
+    -msaa=0          Disable multisampling (default is on)
+    -device=n        Choose GPU to run on
+    -d3d12           Enable D3D12 compute
+    -benchmark       Enable bencmark mode, will write a benchmark.txt to the root folder
+    -vsync=0         Disable vsync
+
