+## VMware CSI Driver Pre-Requisites
+
+In order to sucessfully install the VMware CSI Driver, the following items must be completed first: 
+1. Creation of the `ClusterSecretStore` Kubernetes resource detailed in the eks-anywhere-addons/README.md file 
+
+2. Creation of config secrets in AWS Secrets Manager that External secrets will reference in the 
+vsphere-csi-externalsecrets.yaml file.
+
+# Creation of the Config Secrets 
+
+Two Secrets must be created, csi-vsphere.conf referenced by the 
+vsphere-csi-controller in the vsphere-csi-driver.yaml file, and 
+vsphere.conf that is referenced in the vsphere-cloud-controller.yaml file
+
+Both secrets are multi-line configs, so the "Plaintext" secret type must be used. 
+
+In csi-vsphere.conf, the secret will contain Global configuration data and Virtual Center specific information in the following format:
+
+```
+[Global]
+insecure-flag = "true"
+port = "443"
+
+[VirtualCenter "<Your Vcenter IP Address>"]
+cluster-id = "<Your Cluster ID"
+user = "<Your Vcenter Username>"
+password = "<Your Vcenter Password>"
+datacenters = "<Your Datacenter(s)>"
+```
+
+In vsphere.conf the same information is required, YAML formatted:
+
+```
+global:
+  port: 443
+  insecureFlag: true
+
+vcenter:
+  <Your VCenter Name>:
+      server: <Your Vcenter IP Address>
+      user: <Your Vcenter Username>
+      password: <Your Vcenter Password>
+      datacenters:
+      - <Your Datacenter(s)>
+```
+
