+# vSphere CSI – Base Configuration
+
+This directory contains the base manifests for deploying the vSphere Cloud Storage Interface (CSI) driver, enabling Kubernetes clusters running on VMware vSphere to provision and manage persistent storage natively.  
+It is designed to be consumed by cluster repositories as a remote base, allowing each cluster to apply custom overrides such as StorageClass definitions, topology settings, or credentials.
+
+**About vSphere CSI:**
+
+- Provides dynamic provisioning of PersistentVolumes (PVs) backed by vSphere datastores including vSAN, VMFS, and NFS.
+- Supports advanced features such as volume expansion, snapshots, and cloning.
+- Integrates with vSphere Storage Policy Based Management (SPBM) so Kubernetes PVCs can inherit vSphere storage policies.
+- Enables topology-aware provisioning, ensuring volumes are created in the appropriate zone or failure domain for workload placement.
+- Offloads volume lifecycle operations to vSphere, improving reliability, consistency, and automation.
