+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

+
+## Purpose
+
+This sample program, `minimal`, performs two ray to triangle intersect tests with the Embree API. One test is successful, while the other test is a miss. Output is written to the console (stdout).
+
+## Key Implementation Details
+
+This source code is constructed to build with a C++ or a C compiler.
+
+## License
+
+This code sample is licensed under the Apache 2.0 license. See
+[LICENSE.txt](LICENSE.txt) for details.

+Third party program Licenses can be found here: [third-party-programs.txt](https://github.com/oneapi-src/oneAPI-samples/blob/master/third-party-programs.txt)
+
+## Build and Run
+
+### Windows OS:
+
+Run a new **x64 Native Tools Command Prompt for MSVS 2019**

+mkdir build
+cd build
+cmake ..
+cmake --build . --config Release
+cd Release
+minimal.exe
+```
+
+Review the terminal output (stdout)
+
+
+### Linux OS:
+
+Start a new Terminal session
+```
+source <path-to-oneapi-folder>/setvars.sh
+cd <path-to-oneAPI-samples>/RenderingToolkit/02_embree_gsg
+mkdir build
+cd build
+cmake ..
+cmake --build .
+./minimal
+```
+
+Review the terminal output (stdout)
+
+
+### MacOS:
