-Save the output as `backend.tf` (replacing the key with a unique string), and run `terraform apply` again to migrate the state of this module back to S3.
+1. Save the output config as `backend.tf`
+1. Edit `backend.tf` and copy the `bucket` name to the `key` name.
+1. Run `terraform init`. Answer YES to whether to copy the backend.tf
+1. If it was successful, run `rm terraform.tfstate*`
+1. Run a final `terraform apply`
 
-You can use the output again in other projects.
 
-If you wish to recreate, do _not_ update the config. You must `terraform destroy`, remove `backend.tf`, make changes, then `terraform apply`
+### Later usage
+
+Run `terraform output` to get the config, and copy it as a `backend.tf` in your other projects. Be careful not to reuse the key.

+
+### Making Changes
+
+Once you've migrated the backend to s3, you probably do not want to make changes. Do so at your own risk.
