Fedora new install, what is the repo url please?

Planning on installing Fedora 20 64 bit on a new laptop with an nVidia GT730M card. I know I'm prompted to 'add repos' for the install, but from yum.repos.d in the file I see http://download1.rpmfusion.org/nonfree/fedora/development/$basearch/os/ How should I translate this to add it as a workable url please, and are there more I should add?
