Getting started with Qcow2

I have uploaded my .qcow2 images in /var/lib/vz/images then am stocked and don't know what to do... Should I write a code into the Shell of the node?

You shold import an image to the vm.
Code:
qm importdisk XXX /var/lib/vz/images/image.qcow2 local
Replace XXX by real vm id and replace "local" by real storage name.
