 ### Security Tips
 
-For greatest security, you want to run Docker inside a virtual machine, or on a host.  This is straight from the Docker Security Team Lead -- [slides](http://www.slideshare.net/jpetazzo/linux-containers-lxc-docker-and-security) / [notes](http://www.projectatomic.io/blog/2014/08/is-it-safe-a-look-at-docker-and-security-from-linuxcon/).  Then, run with AppArmor / seccomp / SELinux / grsec etc to [limit the container permissions](http://linux-audit.com/docker-security-best-practices-for-your-vessel-and-containers/).
