What is resources.props and how to work with it?

Hi All,

I have created new JS project with v 3.10. I ran iOS and Android versions, but Windows is something hard for me. I compiled and ran it. That is OK. But I cannot understand how to update resources.
I have found resources.props files and it is added into .vcxproj file as “Import Project” tag. But I cannot find anything related to resources in Solution Explorer.
Can somebody explain what is and how to operate with resources.props? How to add/modify it? Anything. Article, screenshots will be useful.

Regards,
Valery.
