+# Vsphere Example Files
+## Contents
+* *.yaml files - concrete example files that can be used as is.
+* *.yaml.template files - template example files that need values filled in before use.
+
+## Generation
+For convenience, a generation script which populates templates where possible.
+
+1. Run the generation script. This wil produce ```provider-components.yaml```
+```
+./generate-yaml.sh
+```
+2. Copy machines.yaml.template to machines.yaml and
+Manually edit ```terraformVariables``` for machines in machines.yaml
+```
+cp machines.yaml.template machines.yaml
+```
+
+3. Copy cluster.yaml.template to cluster.yaml and
+Manually edit ```providerConfig``` for the cluster in cluster.yaml
+```
+cp cluster.yaml.template cluster.yaml
+```
+
+## Manual Modification
+You may always manually curate files based on the examples provided.
