+# fabric compute example
+
+**__NOTE: THIS RESOURCE TYPE MUST BE IMPORTED. ATTEMPTING TO CREATE IT WILL ERROR__ **
+
+These resources (fabric computes) are discovered in vRA(C) as part of creating a Cloud Account and can not therefore be "created" or "destroyed" in a traditional sense.
+
+This is an example on how to import a fabric compute resource into terraform and then manage settings on it.
+
+## Getting Started
+
+There are variables which need to be added to a `terraform.tfvars` file:
+
+* `url` - The base url for API operations
+* `refresh_token` - The refresh token for API operations
+* `insecure` - Specify whether to validate TLS certificates
+
+To facilitate adding these variables, a sample tfvars file can be copied first:
+
+```shell
+cp terraform.tfvars.sample terraform.tfvars
+```
+
+This examples assumes a cloud account is already set up.
+
+To import the resource you must find the ID of the fabric compute. There are a couple of way this ID can be aquired:
+
+1. Via API calls
+2. Viewing the object in a browser and pulling the ID from the url (ex value: `e2a959f4-7ec5-4941-b532-32b798309feb`)
+
+Once the information is added to `terraform.tfvars` the resource can be imported and the manage via:
+
+```shell
+terraform import vra_fabric_compute.this <computeID>
+```
+
+If the import is successful output from the command should resemble
+
+```shell
+vra_fabric_compute.this: Importing from ID "<computeID>"...
+vra_fabric_compute.this: Import prepared!
+  Prepared vra_fabric_compute for import
+vra_fabric_compute.this: Refreshing state... [id=<computeID>]
+
+Import successful!
+
+The resources that were imported are shown above. These resources are now in
+your Terraform state and will henceforth be managed by Terraform
+```
+
+To apply your settings you can now perform an apply comand:
+
+```shell
+terraform apply
+```
