+Attributes file is optional for connecting via ssh, but required for winrm.

+The following file contains the bare minimum necessary to get winRM working;
+you have to give it the password to give to the "Administrator" user, which 
+will be the one winrm connects to. You must also whitelist your computer
+to connect via winRM -- the empty braces below whitelist any computer to access
+winRM but you can make it more secure by only allowing your build machine 
+access. See the [docs](https://docs.oracle.com/en/cloud/iaas/compute-iaas-cloud/stcsg/automating-instance-initialization-using-opc-init.html#GUID-A0A107D6-3B38-47F4-8FC8-96D50D99379B)
