Is Bootstrap already installed with VS.NET 2015?

I have the VS.NET 2015 CTP. I've created a web app and selected to install a nuget package. I select Twitter.Bootstrap.Less and install. I see a green check mark next to this package in the nuget window. I close this window but don't notice a content folder in my project.

When I open the wwwroot > lib folder, I see:

bootstrap
bootstrap-touch-carousel

Those were there before I installed the bootstrap package.

Does bootstrap come default with web apps in vs.net 2015?

I installed the bootstrap nuget but the content folder isn't there and I don't see any other package downloads. Any idea where the package content went?
