 Convert a GCE service key into a pem (for ansible)
 --------------------------------------------------
 1. mkdir -p ~/.gce
 1. The gce service key looks something like this: projectname-ef83bd90f261.p12
-.. the ef83bd90f261 part is the public hash
+.. The ef83bd90f261 part is the public hash (GCE_KEY_HASH), The projectname part, is the project name (PROJECT_NAME).
 1. Be in the same directory as the p12 key file.
 1. The commands below should be copy / paste-able
 1. Run these commands:
 ```
-   # Temporarily set hash variable
+   # Temporarily set hash variable and project name
    export GCE_KEY_HASH=ef83bd90f261
+   export PROJECT_NAME=projectname
 
    # Convert the service key (note: 'notasecret' is literally what we want here)
-   openssl pkcs12 -in projectname-${GCE_KEY_HASH}.p12 -passin pass:notasecret -nodes -nocerts | openssl rsa -out projectname-${GCE_KEY_HASH}.pem
+   openssl pkcs12 -in ${PROJECT_NAME}-${GCE_KEY_HASH}.p12 -passin pass:notasecret -nodes -nocerts | openssl rsa -out ${PROJECT_NAME}-${GCE_KEY_HASH}.pem
 
    # Move the converted service key to the .gce dir
-   mv projectname-${GCE_KEY_HASH}.pem ~/.gce
+   mv ${PROJECT_NAME}-${GCE_KEY_HASH}.pem ~/.gce
 
    # Set a sym link so it is easy to reference

 ```
 
 1. Once this is done, put the original service key file (projectname-ef83bd90f261.p12) somewhere safe, or delete it (your call, I don not know what else we will use it for, and we can always regen it if needed).
