Installing Free and Non-Free Repositories
If you want to enable access via yum to the free repository, just type the following command:
rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
If you want to enable access to the nonfree repository too, you also need to type this command:
rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
Rawhide
If you installed a Fedora Beta or you use Rawhide then use the following command to enable RPM Fusion free for rawhide:
rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-rawhide.noarch.rpm
And also this one if you want to use non-free too:
rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-rawhide.noarch.rpm
