Installing the template is described toward the bottom of the page in the section entitled Create a New Visual Studio Project.
I have no idea if these are important in the builds.
I went through Joey De Vries excellent OpenGL tutorial without downloading any templates for the library. I did need to put some work to install and access some of the supporting libraries.
It looks like these templates might make building apps a bit easier. I’m just following the instructions as I install the SDK.
I didn’t realize I’d need to search for Vulkan. I was expecting that any templates in a directory designated for holding templates would be listed by default.
