 It will create a Data Volume (DV) and import a cirros virtual disk image to that DV. If you try some of the other examples you might find that some of them require [scratch space](scratch-space.md). To create scratch space you simply need another PV available and CDI will automatically make use of it while importing. For cloning you will also need two PVs, one that contains the source data, and one that will be the target.

 The purpose of this document is to show how to create registry image containing a Virtual Machine image that can be imported into a PV.
 
 ## Prerequisites
-Import from registry should be able to consume the same container images as [containerDisk](https://github.com/kubevirt/kubevirt/blob/master/docs/container-register-disks.md).
+Import from registry should be able to consume the same container images as [containerDisk](https://github.com/kubevirt/kubevirt/blob/main/docs/container-register-disks.md).
 Thus the VM disk image file to be consumed must be located under /disk directory in the container image. The file can be in any of the supported formats : qcow2, raw, archived image file. There are no special naming constraints for the VM disk file.
 
 ## Import VM disk image file from existing containerDisk images in kubevirt repository
