+The 'workspaces' block configures how Terraform CLI maps its workspaces for

+organization. Two strategies are available:
+
+tags - A set of tags used to select remote HCP Terraform or Terraform
+Enterprise workspaces to be used for this single
+configuration. New workspaces will automatically be tagged with these tag
+values. Generally, this
+is the primary and recommended strategy to use.  This option conflicts with
+"name".
+
+name - The name of a single HCP Terraform or Terraform Enterprise workspace
+to be used with this configuration.
+When configured, only the specified workspace can be used. This option
+conflicts with "tags"
+and with the TF_WORKSPACE environment variable.
