 This example would enable the `GuestServiceInterface` (which Vagrant is aware) and `CustomVMSRV` (which
 Vagrant is _not_ aware) VM integration services.
+
+## Attaching extra controllers and disks
+
+The `controller` configuration option is a simple hash that describes what kind of controller it is.
+Such as `:scsi` or `:ide`. Right now only `:scsi` is supported. After this the disks that will be
+created is specified in the `disks` array. This is an array where several disks to create can be
+specified. First comes the name of the disk, for example d1, and after that followes the size of the
+disk specified in MB, for example 10 * 1024 for a 10 GB disk. Repeat this for the number of disks you
+want to attach on the controller. To attach existing vhd- or vhdx-files is not implemented yet.
+
+```ruby
+config.vm.provider "hyperv" do |h|
+  h.controller type: :scsi, disks: [ "d1", 10 * 1024 ]
+end
+```
+
+This example would create a SCSI controller and also create a d1.vhdx file and attach it as a dynamic
+disk that is 10 * 1024 MB big, in other words 10 GB.
