+Usage: terraform import [options] ADDR ID
+
+  Import existing infrastructure into your Terraform state.
+
+  This will find and import the specified resource into your Terraform
+  state, allowing existing infrastructure to come under Terraform
+  management without having to be initially created by Terraform.
+
+  The ADDR specified is the address to import the resource to. Please
+  see the documentation online for resource addresses. The ID is a
+  resource-specific ID to identify that resource being imported. Please
+  reference the documentation for the resource type you're importing to
+  determine the ID syntax to use. It typically matches directly to the ID
+  that the provider uses.
+
+  In the current state of Terraform import, the resource is only imported
+  into your state file. Once it is imported, you must manually write
+  configuration for the new resource or Terraform will mark it for destruction.
+  Future versions of Terraform will expand the functionality of Terraform
+  import.
+
+  This command will not modify your infrastructure, but it will make
+  network requests to inspect parts of your infrastructure relevant to
+  the resource being imported.
+
+Options:
+
+  -backup=path        Path to backup the existing state file before
+                      modifying. Defaults to the "-state-out" path with
+                      ".backup" extension. Set to "-" to disable backup.
+
+  -input=true         Ask for input for variables if not directly set.
+
+  -no-color           If specified, output won't contain any color.
+
+  -state=path         Path to read and save state (unless state-out
+                      is specified). Defaults to "terraform.tfstate".
+
+  -state-out=path     Path to write updated state file. By default, the
+                      "-state" path will be used.
