## Getting Started
25-
- Check out the [source](https://github.com/microsoft/Windows-Machine-Learning/blob/91e493d699df80a633654929418f41bab136ae1d/Samples/WinMLSamplesGallery/WinMLSamplesGalleryNative/OpenCVImage.cpp#L21)
25+
In order to build this sample, OpenCV will need to be built and linked into the WinML Samples Gallery. The OpenCV project is included as a submodule, and will need to be synced and built for your Platform Architecture and Configuration before it will appear in the Windows ML Samples Gallery. To do so follow these instructions:
26+
- Launch a Visual Studio Developer Command Prompt.
27+
- Navigate to root.
28+
- Sync submodules with `git submodule update --init --recursive`
29+
- Launch Powershell with `powershell`
30+
- Build the OpenCV project with
31+
32+
`.\external\tools\BuildOpenCV.ps1 -Architecture <ARCH> -Configuration <CONFIGURATION>`
33+
34+
For example:
35+
36+
`.\external\tools\BuildOpenCV.ps1 -Architecture x64 -Configuration Debug`
37+
- Launch the `WinMLSamplesGallery.sln` and build with the same **Architecture** and **Configuration** to see the sample appear.
38+
39+
40+
You can check out the source [here](https://github.com/microsoft/Windows-Machine-Learning/blob/91e493d699df80a633654929418f41bab136ae1d/Samples/WinMLSamplesGallery/WinMLSamplesGalleryNative/OpenCVImage.cpp#L21).

Please file an issue [here](https://github.com/microsoft/Windows-Machine-Learning/issues/new) if you encounter any issues with this sample.
