Vangelis Katsikaros 94463894ec website: "map" a real resource to configuration, not "attach" (#17912)
In the terraform state documentation the verb "map" is widely used to
describe the relationship between an item in the state and in the real world
whereas the verb "attach" is not used anywhere.

# Import
Terraform is able to import existing infrastructure. This allows you take
resources you've created by some other means and bring it under Terraform
management.
This is a great way to slowly transition infrastructure to Terraform, or
to be able to be confident that you can use Terraform in the future if it
potentially doesn't support every feature you need today.
## Currently State Only
The current implementation of Terraform import can only import resources
into the [state](/docs/state). It does not generate configuration. A future
version of Terraform will also generate configuration.
Because of this, prior to running `terraform import` it is necessary to write
manually a `resource` configuration block for the resource, to which the
imported object will be mapped.
While this may seem tedious, it still gives Terraform users an avenue for
importing existing resources. A future version of Terraform will fully generate
configuration, significantly simplifying this process.
