Modernizr is missing "main" entry in bower.json

I get the above message when i run the npm install - along with
modernizr is missing “ignore” entry in bower.json

is this correct?

It should just be a warning. Are you not seeing the 3rd party assets in assets/vendor/ after bower install?

yes it all seems to be there and working ok, - just getting my head around the new stucture!
