building selinux-policy from source on fedora core

Hi. As i am running fedora core 20 and the updates from rawhide are far than early ported to core i was wondering how to build it from source. Do i just follow the INSTALL guide? It seems it installs as refpolicy while i have targeted and mls or is it something non relevant? Do i have to change the directive module-store to source from direct in /etc/selinux/semanage.conf. Any other issues i should take care of?Thanks
