+#
+# You can skip setting the url if you set the VAULT_ADDR environment variable
+# or if you want it to default to localhost:8200
+#
+# NOTE: Due to a current limitation in the HVAC library there won't
+# necessarily be an error if a bad endpoint is specified.
+#
+# Requires hvac library. Install with pip.
