 The libvirt Resource Provider lets you manage libvirt resources.
 
-## Installing
 
-This package is available in many languages in the standard packaging formats.

+> which can be generated from the Libvirt Terraform provider as follows:
+> `pulumi package add terraform-provider registry.opentofu.org/dmacvicar/libvirt <version>`
+> and follow the instructions.
