+This project shows how to integrate CUDA and OpenGL. Generating the Makefile with CMake
+
+## Expected Output
+
+After building and running the project (see below). You should see this:
+
+![Expected Output](expected_output.png "Expected Output")
+
+## Dependencies
+
+You need to install:
+
+* CUDA SDK
+* OpenGL
+* CMake 3.0+
+
+## How to build (Windows)
+
+To build on windows. Open the command line (or use the cmake gui)
+
+
+* Check your Visual Studio version and change it if needed on the last step
+* The CUDA SDK may be installed as 64bit version. If so, you need to use the `Win64` on the last command, otherwise you can omit it. If you omit it on 64bit versions you won't have access to libraries like: CURand or CUBLAS
+
+```
+    mkdir build
+    cd build
+    cmake .. -G "Visual Studio 12 2013 Win64"
+```
+
+Open the project in Visual Studio.
+
+
+## How to build (MacOS and Linux)
+
+This step couldn't be tested, if you test it email me or create an issue saying
+if it works or not.
+
+```
+    mkdir build
+    cd build
+    cmake ..
+    make
+```
