-A working CentOS 6.x kickstart file can be found [at this
-URL](https://gist.github.com/mitchellh/7328271/#file-centos6-ks-cfg), adapted
-from an unknown source. Place this file in the http directory with the proper
-name. For the example above, it should go into "httpdir" with a name of
-"centos6-ks.cfg".
+This is an example only, and will time out waiting for SSH because we have not
+provided a kickstart file. You must add a valid kickstart file to the
+"http_directory" and then provide the file in the "boot_command" in order for
+this build to run. We recommend you check out the
+[Community Templates](https://www.packer.io/community-tools.html#templates)
+for a practical usage example.
