Just sync the documentation up since the latest [virt7-docker-common-release](http://cbs.centos.org/koji/packages?tagID=112) has newer packages that work together.
Tested this on a single node Centos 7.1 node with the following packages and it all works well so far:
```
yum list -q docker etcd kubernetes flannel
Installed Packages
docker.x86_64 1.8.2-7.el7.centos @extras
etcd.x86_64 2.1.1-2.el7 @extras
flannel.x86_64 0.2.0-10.el7 @extras
kubernetes.x86_64 1.1.0-0.4.git2bfa9a1.el7 @virt7-docker-common-release
