+## Example Usage
+
+```hcl
+data "nsxt_compute_collection" "test_cluster" {
+  display_name = "Compute_Cluster"
+}
+```
+
+## Argument Reference
+
+* `id` - (Optional) The ID of Compute Collection to retrieve.
+* `display_name` - (Optional) The Display Name of the Compute Collection to retrieve.
+* `origin_type` - (Optional) ComputeCollection type like VC_Cluster. Here the Compute Manager type prefix would help in differentiating similar named Compute Collection types from different Compute Managers.
+* `origin_id` - (Optional) Id of the compute manager from where this Compute Collection was discovered.
+* `cm_local_id` - (Optional) Local Id of the compute collection in the Compute Manager.
